Brief Review of Management of Fetal Tachycardia in Pregnancy
Samah Alasrawi, Mohammad Nour Alesrawi and Ahmad Al EsrawiFetal tachycardia is a heart rate greater than 160-180 beats per minute (bpm).1,2, It may be a regular or irregular rhythm which may be intermittent or sustained.3,4,5 Fetal tachycardia is uncommon, (less than 1% of all pregnancies).6,7 Most of the time, fetal arrhythmias discovered as isolated findings; however, 5% of fetuses with arrhythmia will also have congenital heart disease,8,9 such as hypoplastic left heart syndrome , Epstein’s anomaly, atrioventricular canal, or intracardiac tumors. The most important point that the persistent arrhythmias may lead to fetal heart failure, or non-immune hydrops fetalis;10 So 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.
