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.

Catheter ablation plays a pivotal role in the management of atrial fibrillation (AF). Recent randomized controlled studies have shown that catheter ablation is superior to conventional antiarrhythmic medical treatment as first-line therapy in reducing symptoms, AF recurrences, and preventing progression of AF. If the examined antiarrhythmic medical regimens were given in therapeutic and adequate doses remains an open question.

Background: Flecainide is a Class IC antiarrhythmic drug used to treat arrhythmias such as atrial fibrillation (AF), paroxysmal supraventricular tachycardia, and ventricular tachycardia (VT). Its mechanism involves blocking sodium channels, leading to QRS widening, especially at higher heart rates. This property increases the risk of pro-arrhythmic events, particularly in patients with structural heart disease or ischaemia.

Background: Elevated intracardiac filling pressures create a proarrhythmic environment that facilitates the development or progression of atrial fibrillation (AF). Accelerated lower rate pacing results in atrial decongestion by lowering intracardiac filling pressure and therefore may have an antiarrhythmic effect.
Case Summary: A 70-year-old woman with paroxysmal AF on flecainide progressed to symptomatic rate-controlled persistent AF 5 months ago.

Background: Vernakalant is authorized in several countries, except in the U.S., where the FDA denied its commercialization due to safety concerns, generating debate about its use.
