Abstract
Technical aspects and clinical usefulness. Two patients who underwent a ventricular aneurys‐mectomy 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, elec‐trophysiological 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. (PACE. Vol. 5, September‐October, 1982)
