504-514. Fetale Herzfrequenz . The prognosis for hydrops associated with fetal arrhythmia is poor with mortality as high as 50-98%,4,13 compared with 0-4% in cases without evidence of significant failure.6, The primary goal of fetal therapy is the prevention or resolution of hydrops.14,15 This may be achieved by: conversion to sinus rhythm; or ventricular rate control.8,12,16 The use of fetal echocardiography, M-mode and pulse-wave Doppler has lead to improved diagnosis of fetal arrhythmias, and remains the cornerstone of diagnosis.1,6 Fetal magnetocardiography, a non-invasive method for diagnosing complex fetal arrhythmias, is available at limited centers.1,8, Initial medical therapy is delivered transplacentally by administering medication to the mother orally or intravenously. There is concern for dose-dependent contraction of placental vessels with a potential reduction in blood flow.4. Outcome 77 5.7.1. 765-770. Copyright® 2021 Radcliffe Medical Media.

Atrial flutter (AFL), the second most common tachyarrhythmia,11 accounts for 25% of fetal tachyarrhythmias.5 Typical time of presentation is around 32 weeks gestational age but may be noted at delivery.5 The electrophysiologic mechanism of tachycardia is intra-atrial macro-re-entry, similar to adult AFL.6 Overall mortality from AFL is 8%,11 but may be as high as 30% in the hydropic fetus. in utero infection; in utero hypoxia; fetal anemia; chromosomal anomalies.

Congenital Junctional Ectopic Tachycardia (JET), a rare tachyarrhythmia in fetuses, is a slower yet incessant tachycardia with rates of 180-200bpm.20 This arrhythmia can be 1:1 or have a faster ventricular rate than atrial rate and may have a familial occurrence.24, Fetal VT is also quite rare,11 with ventricular rates from 170-400bpm. Ultrasound may also show evidence of associated complications, such as signs of hydrops fetalis.

Ultrasound Diagnosis of Fetal Anomalies. 191-196. In 80% of patients, conduction is 2:111 (see Figure 2), resulting in ventricular rates of 200bpm.4 AFL may progress to 3:1 block, or alternatively may develop intermittent 1:1 conduction.1 The rhythm is irregular and persistent, and is associated with fetal hydrops in 7-43% of cases.1 AFL may be associated with congenital heart disease or chromosomal abnormalities.5, As in the treatment of fetal SVT, digoxin is used as first-line therapy for non-hydropic fetal AFL.11 Studies have shown that sotalol (pregnancy category B; anti-arrhythmic class III) is efficacious in the treatment of fetal AFL,2,6 and less effective for SVT.

Persistent junctional reciprocating tachycardia (PJRT) is a slow form of AVRT.The accessory pathway has very slow retrograde conduction conduction6 with the usual obligatory 1:1 atrioventricular association seen in faster AVRT.7 This uncommon arrhythmia has rates around 180-220bpm.7,8 Since it is generally incessant, hydrops can be associated with this arrhythmia.
