Telemetry of Intracardiac Electrograms: Applications in Spontaneous and Induced Arrhythmias (original) (raw)

LUCERI R: Telemetry of intracardiac electrograms: Applications in spontaneous and induced arrhythmias, hi order to demonstrate the feasibility of di/srhythmia analysis by means of noninvasive intracardiac telemetry, a custom-modified AFP DDD pulse generator was attached to teniporari/ fiacing 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 of intracardiac electrograms may have a prominent role in the design of multifunction devices for both bradycardias and tachycardias.
