Radiofrequency current was utilized to mark the anatomic location of earliest endocardial activation during catheter mapping of ventricular tachycardia. Intraoperative identification of the radiofrequency lesion allowed validation that the site of earliest endocardial activation determined by a catheter mapping study was the same as assessed by a computerized balloon mapping system, fladiofrequency current may be a useful method of marking areas of endocardium thought to be potential sites for ablative surgery as well as allowing correlation between different mapping techniques.
