Abstract: | 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. |
