Abstract
In order to demonstrate the feasibility of dysrhythmia analysis by means of noninvasive intracardiac telemetry, a custom‐modified AFP DDD pulse generator was attached to temporary pacing electrodes in 15 patients undergoing electrophysiology studies for a variety oftacliy‐ or bradyarrhythmias. Intracardiac atrial and ventricular electrograms were obtained during induction, termination, and drug intervention in patients with these arrhythmias. The telemetered computer‐generated hardcopy tracings compared favorably to those obtained through a standard multichannel physiological recorder, and thus confirmed the accuracy of the technique. Therefore, microprocessor‐based telemetry ofintracardiac electrograms may have a prominent role in the design of multifunction devices for both bradycardias and tachycardias
