Postoperative electrophysiological studies with a modified radiofrequency system. Technical aspects and clinical usefulness.
Two patients who underwent a ventricular aneurysmectomy for treatment of ventricular tachycardia are presented. In both patients, a radiofrequency pacemaker was implanted at surgery (for therapeutic use if surgery should fail). In both patients, electrophysiological studies were performed before discharge utilizing a radiofrequency pacemaker without recourse to repeat catheterization. This was possible by modifying the transmitter and coupling it to a commercially available programmable stimulator.
