Abstract:
A safe approach to radiofrequency catheter ablation is still unclear and not well defined in patients with AV nodal reentrant tachycardia and prolonged PR interval. In our study, a patient with iterative AV nodal reentrant tachycardia and prolonged PR interval underwent fast pathway radiofrequency catheter ablation. By mapping Koch's triangle, the earliest retrograde atrial activation area was localized. Radiofrequency energy was delivered here with the interruption of tachycardia with no complications.

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.
