Entrance Site in ILVT. The entrance site of the slow conduction zone was identified by entrainment study in an 18 year‐old woman with verapamil‐sensitive idiopathic left ventricular tachycardia. Radiofrequency catheter ablation at this site eliminated the tachycardia. The entrance site was at a mid‐septal location and was more than 2 cm away from the exit site. Electrophysiologic findings suggested macroreentry in the Purkinje system as the mechanism of idiopathic left ventricular tachycardia.
