Fetal tachyarrhythmias, particularly supraventricular tachycardia (SVT) and atrial flutter (AFL), pose significant clinical challenges, especially when complicated by hydrops fetalis. This article provides a comprehensive review of the tachyarrhythmia types, the diagnostic modalities applied, and the therapeutic strategies followed in fetal tachyarrhythmias. Diagnostic techniques such as M-mode echocardiography and fetal magnetocardiography (fMCG) are highlighted for their capacity to provide real-time, high-quality assessments of fetal cardiac rhythms.

Fetal arrhythmias account for 10-20% of all outpatient consultations in specialized fetal medicine centers. Furthermore, it is evident that tachyarrhythmias account for 8% of all such arrhythmias. Most arrhythmias are benign and easy to manage, but certain tachyarrhythmias require close monitoring due to the risk of decompensation, progression to heart failure with hydrops, and potential fetal death.

Background: Sustained fetal tachycardia requires transplacental anti-arrhythmic therapy. Little is known about the dose-concentration-effect correlation and safety in the mother, fetus, and newborn.
Objective: This study evaluates the relationship between maternal dose of digoxin and flecainide therapy for fetal tachycardia, maternal and umbilical cord concentrations, and side effects.

Introduction: Sustained fetal tachycardia is an uncommon phenomenon in gestations (approximately 0.1%). Atrial flutter (AF) accounts for 10-30% of fetal tachyarrhythmias, which is characterized by a rapid atrial rate estimated at 300-600 beats per minute, associated with variable degrees of atrioventricular conduction.
