Late complete atrioventricular block complicating radiofrequency catheter ablation of a left posteroseptal accessory
Abstract:
A patient with AV reentrant tachycardia underwent radiofrequency catheter ablation for interruption of a left posteroseptal accessory pathway (AP). During the RF current application, he developed transient complete left bundle branch block which lasted for 2 minutes. The following day the patient developed permanent complete AV block. This case indicates that great care should be taken when performing RF ablation for this AP site.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
