Abstract:
Radiofrequency ablation was attempted in a 17-year-old man with atrioventricular node re-entry of the common variety. Energy was delivered to three sites around the ostium of the coronary sinus. The third attempt resulted in a sudden increase in AH interval with loss of retrograde conduction. The arrhythmia was no longer inducible. These observations may suggest the unusual location of the fast pathway.
