Abstract

A 39-year-old man with a seemingly non-remodeled, small heart suffered persistent atrial fibrillation (AF). Extensive isolation of the pulmonary vein, superior vena cava, and posterior left atrium, in conjunction with right atrium focal ablation, was performed to ablate multiple AF foci during two catheter ablation sessions. Sinus arrest occurred suddenly during follow-up, despite the absence of recurrent AF, ultimately necessitating pacemaker implantation. This case underscores the necessity of careful follow-up after catheter ablation, highlighting the risk of sudden, severe sinus node dysfunction, even in young AF patients with small hearts.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
