A 65-year-old man developed syncope following palpitation during an outdoor activity in the daytime. The 12-lead electrocardiogram (ECG) showed Brugada-type ST segment elevation. Holter ECG monitoring documented an episode of regular wide QRS tachycardia. During an electrophysiologic study (EPS), ventricular tachyarrhythmia was not induced. However, a common (slow-fast) type atrioventricular nodal reentrant tachycardia with aberrant ventricular conduction, which was the same configuration as

The patient has been asymptomatic for the 12-month follow-up after the successful slow pathway ablation. This patient reminds us of the importance of EPS in the differential diagnosis of a wide QRS tachycardia. (J Arrhythmia 2007; 23: 285-288)
