how could a fetal arrhythmia affect fetal oxygenation?shark attacks in pensacola, florida

In other situations, a newborn may have a structural abnormality and dysrhythmia. Strasburger JF, et al. Atrial contractions (A) are identified by the start of the A-wave in the renal vein Doppler waveform and ventricular contractions (V) by the renal artery flow. Our Commitment to Diversity, Equity and Inclusion (DEI), Congenital (present at birth) heart defects. The FHR is under constant variation from the baseline (Figure 1). All rights reserved. Specifically, it then reviews the maternal, fetal, and placental factors . The authors recommend for the mother to stop known or suspected inciting factors, such as smoking, excessive caffeine ingestion, and cardiac active drugs (b-mimetics for premature contractions), when possible. Fetal arrhythmias are classified into three main groups: irregular cardiac rhythm, fetal bradyarrhythmias (below 100 beats/min), and fetal tachyarrhythmias (above 180 beats/min). On very rare occasions, premature beats originate from the ventricle rather than the atrium and are thus termed premature ventricular contractions (PVCs). Genetic syndromes associated with congenital heart disease. The normal FHR range is between 120 and 160 beats per minute (bpm). DiLeo, G. (2002). Doctors diagnose fetal arrhythmias in 13% of pregnancies. They are the most commonly encountered patterns during labor and occur frequently in patients who have experienced premature rupture of membranes17 and decreased amniotic fluid volume.24 Variable decelerations are caused by compression of the umbilical cord. The M-mode cursor line intersects the right atrium (RA), the interventricular septum (S), and the left ventricle (LV). For example, a complete block that causes a dangerous drop in the heart rate is present in around 1 in 20,000 births in the United States. If the PACs are conducted, the ventricles have extra contractions, and this sounds like intermittent extra heart beats. (2013). Neonatologists will be present to assess your baby and start treatment if necessary, or bring him or her to the neonatal intensive care unit (NICU). We treat all forms of arrhythmia at Texas Childrensfrom the most common to the extremely rare. As antibody levels rise, the baby is at an increased risk for complete heart block. The long-term outcome depends on the type of rhythm abnormality and whether other non-cardiac defects are present. (2020). 2. To find out more about fetal arrhythmia and heart conditions that affect children, including finding support groups, a person can ask a primary physician or cardiologist for recommendations. If things are stable or improve on their own, no further treatment may be necessary. (2021). Compiled using information from the following sources: 1. BosqueReal desde 162 m 2 Precios desde $7.7 MDP. While most PACs are harmless and usually resolve over time, approximately 1% of fetuses with PACs will have significant structural heart disease. Your health care providers first step will be to monitor the heart rate and well-being of your baby. Bradycardia in the range of 100 to 120 bpm with normal variability is not associated with fetal acidosis. Clinically, loss of beat-to-beat variability is more significant than loss of long-term variability and may be ominous.18 Decreased or absent variability should generally be confirmed by fetal scalp electrode monitoring when possible. There are two types of fetal arrhythmias: Fetal bradycardia is a slower heart rate than expected. It's typically diagnosed after an individual develops multiple pregnancies at once. Fetal tachycardia is a faster heart rate than expected. (Its also important to note that fetal heart rates can change, and theyre also variable from beat to beat.). They usually resolve without treatment or harm. Auscultation of the fetal heart rate (FHR) is performed by external or internal means. In this article, the clinical diagnosis and treatment of fetal arrhythmias are presented, and advantages and disadvantages of antiarrhythmic agents for fetal arrhythmias are compared. Stephenson, E. (2010, March 19). They resemble the letter U, V or W and may not bear a constant relationship to uterine contractions. The characteristics of first-, second-, or third-degree (complete) heart block are presented in Table 33.1. The demonstration of tricuspid regurgitation on color Doppler or a smaller A-wave in the inferior vena cava on pulsed Doppler concurrent with an ectopic beat may suggest a ventricular origin (13). They are characteristically variable in duration, intensity and timing. If the heart beats too fast, contractions are shallow and not enough blood is pumped with each heartbeat. Maternal caffeine consumption and pregnancy outcomes: a narrative review with implications for advice to mothers and mothers-to-be. The trigeminy is also clearly seen in the umbilical artery pulsed Doppler spectrum (B). Early decelerations are caused by fetal head compression during uterine contraction, resulting in vagal stimulation and slowing of the heart rate. To be classified as sustained bradycardia, your babys heart rate must remain low for 10 minutes or more when monitored. Accelerations are transient increases in the FHR (Figure 1). These medications are given to pregnant mothers and pass to the fetus through the placenta. This noninvasive imaging test allows doctors to see and hear a babys developing heart. M-mode ultrasound, in addition to color and pulsed Doppler echocardiography, plays a significant role in our ability to diagnose complex arrhythmias in the fetus and in monitoring the success of prenatal treatment intervention. Our website services, content, and products are for informational purposes only. Rafi, J. Ko JM. Heart Rhythm Problems (Arrhythmias). We also explore the electrical impulses and. Usually, abnormal heart rhythms have little or no effect on the fetus. An arrhythmia is an irregular heart rate too fast, too slow, or otherwise outside the norm. Evaluation of fetal well-being using fetal scalp stimulation, pH measurement, or both, is recommended for use in patients with nonreassuring patterns.11,12 Evaluation for immediate delivery is recommended for patients with ominous patterns. Of all tachyarrhythmias, atrial flutter and SVT heart rate between 220 and 300 beats per minute are the most common types you may see. However, doctors will monitor them closely as they may lead to proxysmal ventricular tachycardias (VTs). And babies who are treated in the womb may not need any special support or medication after birth or beyond the newborn period. Arrhythmia most often refers to an irregular heartbeat, while dysrhythmia represents all types of abnormal heartbeats: the heartbeat can be too fast (tachycardia) or too slow (bradycardia). Also, arrhythmia may, at some point in development, be normal. Fetal arrhythmia is rare. These can include tachycardiaan increased heart rateor bradycardia, which is a slowed heartbeat. (2020). It is a structural difference present from birth. Another 0.5% will develop supraventricular tachycardia. from the fetal blood so helping to "repay" a fetal oxygen debt.1 The causes of fetal hypoxia and therefore acidosis can be divided into maternal, placen-tal, or fetal. When it occurs earlier in pregnancy, it may be the result of other problems and may lead to heart failure and even fetal death. This can be performed during the newborn period if necessary. You will most likely be able to hold your baby after delivery. Shorter periods of slow heart rate are called transient fetal decelerations and may be benign, especially in the second trimester. This test is noninvasive and is generally done as an abdominal ultrasound by a trained sonographer. Blocked premature beats are typically benign and tend to resolve with increased fetal activity. A PAC that doesnt send a signal to the ventricle is called a non-conducted PAC. Keywords . The rhythm of the heart is controlled by the sinus node (known as the pacemaker of the heart) and the atrioventricular node (AV node). Zaidi, A., & Ro, P. (n.d.). The descent and return are gradual and smooth. Identify baseline fetal heart rate and presence of variability, both long-term and beat-to-beat (short-term). Sustained fetal bradyarrhythmias or tachyarrhythmias, which are associated with an increase in neonatal morbidity and mortality, account for less than 10% of referrals (2). The M-mode cursor is often placed to intersect an atrium and a ventricle so that the relationship of atrial-to-ventricular contractions is recorded (Fig. Significant progress is under way, and future technologic improvements in this field will undoubtedly facilitate the use of fetal ECG in the classification of arrhythmias. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Pregnancy outcomes in patients with autoimmune diseases and anti-Ro/SSA antibodies. With SVT, the heart beats too fast, either because of an abnormal connection between the top and bottom of the heart, or many extra heartbeats coming from the top of the heart. These can include tachycardia-an increased heart rate-or bradycardia, which is a slowed heartbeat. Data and statistics on congenital heart defects. 1 Fetal arrhythmias accounted for 2% of unselected pregnancies 2 and for as much as 16.6% of high-risk pregnancies from 21 gestational weeks to term. how could a fetal arrhythmia affect fetal oxygenation? These extra beats try to signal the AV node, which sometimes works (called conducted) and sometimes does not (called nonconducted). The true sinusoidal pattern is rare but ominous and is associated with high rates of fetal morbidity and mortality.24 It is a regular, smooth, undulating form typical of a sine wave that occurs with a frequency of two to five cycles per minute and an amplitude range of five to 15 bpm. If the PACs are nonconducted, this can cause short intermittent slowing of the heart beat while the heart recovers; this may sound like an intermittent slow heart rate. Risk factors for progression of PACs to tachycardia include low ventricular rate due to multiple blocked atrial ectopic beats and complex ectopy, including bigeminy (Fig. (2017). A PVC disrupts the normal heart rhythm of the fetus, causing an irregular heart rhythm. These antibodies can cause inflammation in the fetal heart, blocking the AV nodes ability to react to the sinus node. Not all fetal arrhythmias require special treatment. Most arrhythmias are not dangerous, but some are concerning. PACs or PVCs that occur in isolation may not require any kind of treatment and may actually resolve on their own before your baby is born. Identify type of monitor usedexternal versus internal, first-generation versus second-generation. Oyen N, et al. Our phones are answered 24/7. The fetal heart rate undergoes constant and minute adjustments in response to the fetal environment and stimuli. Cesarean section may be necessary for obstetrical reasons, however. Fetal magnetocardiography (fMCG) is not yet widely available. Less commonly, open heart surgery may be necessary to correct the cause of an abnormal heartbeat-for example, by destroying the nerves that are abnormally firing impulses to the heart. Get the latest on vaccine information, in-person appointments, video visits and more. Late decelerations are associated with uteroplacental insufficiency and are provoked by uterine contractions. The majority of fetuses with irregular cardiac rhythms are found to have premature atrial contractions (PACs) (Fig. Follow-up is suggested on a weekly or biweekly schedule to monitor fetal cardiac rate and rhythm in order to detect progression to fetal tachycardia, which may necessitate fetal therapy. Bravo-Valenzuela NJ, et al. It is recommended that mothers deliver in a hospital that has immediate access to a specialized neonatal intensive care unit (NICU), with a pediatric cardiologist and other specialists present. 1. In the remaining 60%, no structural fetal anomaly is found and heart block is almost always caused by a connective tissue disease (immune mediated) of the mother. More information on optimizing tissue Doppler display is presented in Chapter 14. Atrial (A) and ventricular (V) contractions are in triplets (double-sided arrows) with a longer pause between the triplet sequence. Figure 33.2: Color Doppler M-mode recording of normal sinus rhythm in a fetus. Typical treatment is oral anti-arrhythmic medicine taken by mom which is carried across the placenta to the fetus. The most common cause of heart block is when mom is carrying antibodies associated with lupus or Sjogrens syndrome (autoimmune conditions). Of these arrhythmias, 10% are considered potential sources of morbidity. Some studies have stated that maternal oxygen supplementation can alleviate abnormal patterns of fetal heart rate (FHR) but does not improve fetal acid-base status . Srinivasan S, et al. However, your doctor may want to monitor your baby closely because some types may indicate a heart defect. Figure 33.12: M-mode recording of a fetus with complete heart block. Postdate gestation, preeclampsia, chronic hypertension and diabetes mellitus are among the causes of placental dysfunction. Irregular fetal cardiac rhythm is the leading cause for referrals to fetal echocardiography centers for rhythm disturbances, and the vast majority of those are benign atrial ectopic beats. In general, heart arrhythmias are grouped by the speed of the heart rate. If your doctor detects an irregular heart rate at your appointment, you may be referred to a specialist to monitor your babys heart through the rest of your pregnancy. Srinivasan, S. & Strasburger, J., Overview of Fetal Arrhythmias. External monitoring is performed using a hand-held Doppler ultrasound probe to auscultate and count the FHR during a uterine contraction and for 30 seconds thereafter to identify fetal response. If doctors can make an accurate diagnosis of fetal arrhythmia, they can select the best treatments for a baby before and after its birth. Since such technology is not technically feasible in the fetus, a more practical approach to the classification of fetal arrhythmias is used, which relies on ultrasound-derived technologies, such as M-mode, pulsed Doppler, and tissue Doppler. Fetal arrhythmias are relatively common and account for 1020% of referrals to fetal cardiology. Congenital heart blocks are also called atrioventricular blocks and there are different degrees. The monitor calculates and records the FHR on a continuous strip of paper. Diagnosis and treatment of fetal cardiac disease. If your doctor suspects fetal arrythmia, you need to consult a fetal cardiologist immediately. A condition where the sinus node and the AV node are not communicating very well. Fetal arrhythmia: Prenatal diagnosis and perinatal management. Conclude whether the FHR recording is reassuring, nonreassuring or ominous. The baseline rate is interpreted as changed if the alteration persists for more than 15 minutes. This content is owned by the AAFP. Fetal cardiac assessment, however, is warranted when PVCs are encountered. And transient arrhythmias those that come and go are more common than sustained arrhythmias, ones that are present always or more often than not. Without treatment, these conditions may lead to a buildup of fluid in your babys body/tissues (hydrops fetalis), preterm delivery, or even death. Your doctor may discover this anomaly when doing a routine ultrasound or listening to your babys heart with a Doppler device. Prematurity, maternal anxiety . Since variable and inconsistent interpretation of fetal heart rate tracings may affect management, a systematic approach to interpreting the patterns is important. Table 4 lists recommended emergency interventions for nonreassuring patterns.4,14 These interventions should also be considered for ominous patterns while preparations for immediate delivery are initiated. The cause of PVCs is unknown in most cases. Electronic fetal heart rate monitoring (EFM) was first introduced at Yale University in 1958.1 Since then, continuous EFM has been widely used in the detection of fetal compromise and the assessment of the influence of the intrauterine environment on fetal welfare. Hunter LE, et al. We monitor this condition by fetal echocardiography to determine if the atria and ventricles are communicating with each other. Lorem ipsum dolor sit nulla or narjusto laoreet onse ctetur adipisci. We are currently involved in a research study investigating home monitoring, home ultrasound and whether or not early administration of steroids is effective. Sinus node dysfunction can result from genetic abnormalities or from damage to a normal sinus node from infections or antibodies. 33.10) or trigeminy (Fig. Less than 2 percent of fetal heartbeat irregularities represent true cardiac arrhythmias. Other rare risks associated with EFM include fetal scalp infection and uterine perforation with the intra-uterine tocometer or catheter. 6. It is also characterized by a stable baseline heart rate of 120 to 160 bpm and absent beat-to-beat variability. 2004-2023 Healthline Media UK Ltd, Brighton, UK, a Red Ventures Company. PACs can be either conducted or blocked, resulting in an irregular rhythm or a short pause, respectively. Supraventricular Tachycardia (SVT) Complete Heart Block. Most babies, however, can wait until they are a little older and stronger. periodic accelerations can indicate all of the following except: A. Stimulation of fetal chemoreceptors B. Tracing is maternal C. Umbilical vein compression A. Stimulation of fetal chemoreceptors All of the following are likely causes of prolonged decelerations except: A. Irregular fetal cardiac rhythm is the leading cause for referrals to fetal echocardiography centers for rhythm disturbances, and the vast majority of those are benign atrial ectopic beats. Fetal cardiac arrhythmias: current evidence. M-mode (motion-mode) echocardiography is obtained by recording ultrasound beam reflections in relation to depth from the transducer and time. In the United States, an estimated 700 infant deaths per year are associated with intrauterine hypoxia and birth asphyxia.5 Another benefit of EFM includes closer assessment of high-risk mothers. 33.3), pulmonary artery and vein (Fig. Is the ketogenic diet right for autoimmune conditions? It might occur when a pregnant person: Fetal supraventricular tachycardia (SVT) is the most common type of fetal tachycardia. Fetal arrhythmia. With proper intervention, most babies with arrhythmias can live full and normal lives. Variable decelerations are shown by an acute fall in the FHR with a rapid downslope and a variable recovery phase. Identify changes in the FHR recording over time, if possible. Complete heart block is usually permanent. Immediate appointments are often available. Atrial tachycardia (AT) occurs when the hearts upper chambers, the atria, beat too quickly. Read about the causes of swollen feet during pregnancy and the treatments and home remedies. Tissue Doppler imaging is a relatively new technique that allows direct analysis of segmental wall motion (myocardial velocities) in any area of the fetal heart during the same cardiac cycle (7). (n.d.) Uncomplicated fetal tachycardia in labour: dilemmas and uncertainties. Fetal cardiac arrhythmia detection and in utero therapy. The normal FHR range is between 120 and 160 beats per minute (bpm). on georgia law on drug testing newborns 2019; whole health recovery . This is typically corrected with medication that you take and pass to your baby through the placenta. Babies can be diagnosed with arrhythmia before they are born. Untreated fetal arrhythmias can lead to hydrops, cardiac dysfunction, or death of the unborn baby. If the fetus does not appear to suffer, an abnormal fetal rhythm is most often closely monitored before birth. Limitations of this technology include its lack of availability in many centers and the need for a magnetically shielded room (10, 11). If the results are abnormal, you may be referred to a maternal-fetal medicine specialist for additional monitoring throughout your pregnancy. Tachycardia is considered mild when the heart rate is 160 to 180 bpm and severe when greater than 180 bpm. Determine whether accelerations or decelerations from the baseline occur. Its not serious, The Epstein-Barr virus (EBV), or human herpes virus 4, is a part of the human herpes virus family and is, Establishing Paternity with Paternity Tests, Can I get pregnant ifand other questions about conception, Products & Tests to Support Your Pregnancy, Supplements and Medications for a Healthy Pregnancy. It is suggested that pregnant women limit their caffeine intake to 200mL of caffeine a dayroughly the amount found in one cup of coffee. Fetal tachycardia, the most common of the rhythm defects, occurs in approximately one in 200 pregnancies. The anxious parents Guide to Pregnancy (p. 108). Sometimes, it can indicate or cause a significant problem. What is the normal fetal heart rate? (2013). Unfortunately, precise information about the frequency of false-positive results is lacking, and this lack is due in large part to the absence of accepted definitions of fetal distress.7 Meta-analysis of all published randomized trials has shown that EFM is associated with increased rates of surgical intervention resulting in increased costs.8 These results show that 38 extra cesarean deliveries and 30 extra forceps operations are performed per 1,000 births with continuous EFM versus intermittent auscultation. PACs are due to atrial ectopic beats (atrial ectopy), which occur most commonly in the late second trimester of pregnancy through term and are usually benign. Steroids can sometimes be used to slow the progression to complete heart block when antibodies are the cause, but the results are not conclusive. Reassuring patterns correlate well with a good fetal outcome, while nonreassuring patterns do not. 33.6). Additional monitoring allows your doctor to keep an eye on your baby and develop a treatment plan for during or after pregnancy, if necessary. Fetal Arrhythmia/Dysrhythmia A healthy fetus has a heartbeat of 120 to 160 beats per minute, beating at a regular rhythm. The FHR recordings may be interpreted as reassuring, nonreassuring or ominous, according to the pattern of the tracing. The M-mode display is therefore a linear representation of adjacent cardiac structures as a function of time. A baby may require further treatment if the arrhythmia does not resolve on its own. coconut milk smells like sulfur what happened to tom from choccywoccydoodah midland women's soccer roster The difficulty of this technique involves the ability to isolate the fetal signals from the overlapping maternal ECG signals. Other maternal conditions such as acidosis and hypovolemia associated with diabetic ketoacidosis may lead to a decrease in uterine blood flow, late decelerations and decreased baseline variability.23. The onset and peak of atrial and ventricular contractions are not clearly defined on M-mode, which limits its ability to measure atrioventricular (AV) time intervals, a major limitation of M-mode evaluation of fetal rhythm abnormalities. This pregnancy-friendly spin on traditional chili is packed with the nutrients your body needs when you're expecting. Donofrio MT, et al. The M-mode cursor line intersects the right ventricle (RV), the interventricular septum (S), and the left ventricle (LV). Any decrease in uterine blood flow or placental dysfunction can cause late decelerations. Fetal bradycardia is defined as a baseline heart rate less than 120 bpm. For . Reduced blood flow to the fetus can affect how much oxygen they receive. A fetal arrhythmia may be diagnosed when a developing babys heart rate falls outside the normal range of 120 to 180 beats per minute (BPM). Heart block can also be associated with some congenital heart diseases including congenitally-corrected transposition of the great arteries and heterotaxy (abnormal arrangement of organs in the chest and abdomen). Stimulation of the peripheral nerves of the fetus by its own activity (such as movement) or by uterine contractions causes acceleration of the FHR.15. Each case of fetal arrhythmia is different, and not all fetal arrhythmias require treatment. They include: The most common type of fetal arrhythmia is premature contractions or PCs. metea valley high school map; horse barn kits near hamburg; habit breaking appliance for tongue thrusting; kontoor brands nottingham address; senate bill 25 pennsylvania The FHR tracing should be interpreted only in the context of the clinical scenario, and any therapeutic intervention should consider the maternal condition as well as that of the fetus. Fetal tachycardia may be a sign of increased fetal stress when it persists for 10 minutes or longer, but it is usually not associated with severe fetal distress unless decreased variability or another abnormality is present.4,11,17. How common is it? If your doctor suspects your baby has an arrhythmia, you may be sent for more detailed imaging called a fetal echocardiogram. Fetal arrhythmia is an abnormal fetal heartbeat or rhythm. The presence of PACs in fetuses with evidence of cardiac dysfunction should alert for the possibility of supraventricular tachycardia (SVT). This article explains how doctors diagnose a fetal arrhythmia, the different types, possible causes, and treatments. In these cases, your team will monitor your pregnancy closely. The presence of a saltatory pattern, especially when paired with decelerations, should warn the physician to look for and try to correct possible causes of acute hypoxia and to be alert for signs that the hypoxia is progressing to acidosis.21 Although it is a nonreassuring pattern, the saltatory pattern is usually not an indication for immediate delivery.19. how could a fetal arrhythmia affect fetal oxygenation? Copyright 1999 by the American Academy of Family Physicians. In animal studies, administration of amiodarone to rabbits, rats, and mice during organogenesis resulted in embryo-fetal toxicity at doses less than the maximum recommended human maintenance . If the babys heart rate is consistently high, your doctor may prescribe you medication that is passed through the placenta to the baby to help regulate the heartbeat. You can learn more about how we ensure our content is accurate and current by reading our. Detailed analysis of the type of arrhythmia in utero is possible using M-mode and Doppler echocardiography. Variable and inconsistent interpretation of tracings by clinicians may affect management of patients. The most common form of this condition is called supraventricular tachycardia (SVT), in which the heart rate can be faster than 200 beats per minute. Fetal arrhythmia is an abnormal fetal heartbeat or rhythm. The most important risk of EFM is its tendency to produce false-positive results. Sometimes, if your baby is close to term, we will go ahead and deliver. Arrhythmia most often refers to an irregular heartbeat, while dysrhythmia represents all types of abnormal heartbeats: the heartbeat can be too fast (tachycardia) or too slow (bradycardia). Finally, the recovery phase is due to the relief of the compression and the sharp return to the baseline, which may be followed by another healthy brief acceleration or shoulder (Figure 8). Maintaining fetal oxygenation to preserve fetal viability and sustain fetal growth throughout pregnancy involves the complex interrelationship between the fetus, the placenta, and the pregnant woman. Lets talk about the more typical conditions. The M-mode cursor line intersects the left ventricle (LV) and right atrium (RA). Many fetal arrhythmias resolve on their own and dont require treatment. This pattern is most often seen during the second stage of labor. when did the mixing bowl close Menu Menu. Though your baby will need to be on medication to regulate the heartbeat for the first few months of life, most rhythm abnormalities have excellent outcomes. Fetal scalp sampling for pH is recommended if there is no acceleration with scalp stimulation.11. Doctors will monitor the health of the fetus and the pregnant person throughout pregnancy and after childbirth. There are two types of fetal arrhythmias: Fetal arrhythmia is rare. Fetal echos can be performed as early as 12 weeks into pregnancy but are more reliable after the 17- to 18-week mark. Arrhythmias are discovered in about 1% of fetuses. german bakery long island. Doctors can use fMCG to help diagnose heart arrhythmias in fetuses at around 20 weeks gestation and older. Fetal arrhythmias and conduction disturbances can be caused by ischemia, inflammation, electrolyte disturbances, stresses, cardiac structural abnormality, and gene mutations. Fetal arrhythmia and anxiety in pregnant women have also been linked. The normal heart rate for a fetus is anywhere between 120 and 160 beats per minute. Most patients who undergo internal fetal monitoring during labor accept monitoring as a positive experience.6. (2014). (2018). This is followed by occlusion of the umbilical artery, which results in the sharp downslope. In most cases, your newborn will receive medications to regulate the heartbeat. A fetal Doppler test normally takes place during your second trimester (weeks 13 to 28 of pregnancy ). In some cases, healthcare providers may not be able to pinpoint the source, especially if the abnormal rhythm is transient. B: Tissue Doppler measurement of longitudinal annular movement velocities in a normal fetus at 20 weeks gestation. Retrieved August 15, 2014. They take various factors into account before choosing treatments, including maternal health and the severity of the condition. Doctors will perform an electrocardiogram (EKG) if they hear an irregular heartbeat after birth.
