Intramyocardial electrograms from spontaneous and paced heart beats, telemetrically recorded from different right ventricular positions

Intramyocardial electrograms from the spontaneously beating and the paced heart were recorded in 8 heart transplants for rejection monitoring, using telemetric dual chamber pacemakers and two epimyocardial leads, located at two different right ventricular positions. Linear regression analysis of the rejection sensitive parameters showed that the correlation between the two electrodes was significantly higher for the paced than for the spontaneous heart beats.
