Abstract
Among various electrocardiographic variables, the QRS duration in V-2 was f ound to be the best discriminator of outcome in patients undergoing radiofr equency catheter ablation of the right ventricular outflow tract tachycardi a and/or bigeminy. If the QRS duration is <160 ms in lead V-2, the probabil ity of successful ablation is lower than if the QRS duration is longer.
