Ms. Wen et al., DETERMINANTS OF TACHYCARDIA RECURRENCES AFTER RADIOFREQUENCY ABLATIONOF IDIOPATHIC VENTRICULAR-TACHYCARDIA, The American journal of cardiology, 81(4), 1998, pp. 500
Clinical and electrophysiologic parameters were analyzed to define the
factors potentially related to tachycardia recurrences in 79 patients
undergoing successful radiofrequency ablation of idiopathic right or
left ventricular tachycardia. It was found that the endocardial activa
tion time at the successful ablation site was the only independent pre
dictor of tachycardia recurrences.
