RF Ablation‐Induced Bezold‐Jarisch Phenomenon. We report a case of asystole induced by radiofrequency (RF) ablation via the coronary sinus in a 35‐year‐old man suffering from symptomatic left posteroseptal accessory pathway. RF application provoked progressive slowing of the sinus rhythm, disappearance of the preexcitation, and an 8‐second period of asystole followed by atrial fibrillation. The causal mechanism proposed is a strong stimulation of va‐gal afferent pathways linked with sensory endings of the inferoposterior myocardial wall leading to a Bezold‐Jarisch‐like phenomenon.
