Abstract:
Functional bradycardia, characterized by a heart rate below the normal range due to dysregulation of the autonomic nervous system (ANS), poses a clinical challenge with limited treatment options. Symptomatic sinus bradycardia is an uncommon but potentially significant complication following bariatric surgery. Cardioneuroablation (CNA) has emerged as a novel therapeutic intervention targeting the cardiac ANS to modulate heart rate. This case series describes two patients, with the aim of providing a simplified but successful approach with targeted partial CNA for sinus bradycardia complicating bariatric surgery.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
