Abstract

Intramyocardial electrograms have been recorded noninvasively via telemetric pacemakers from spontaneously beating heart transplants. The amplitudes of premature QRS complexes have been compared to those of normal QRS complexes. Linear regression analysis revealed increased amplitudes, which are assumed to be due to the reduced filling pattern of the premature beats. Hence, intramyocardial electrograms contain haemodynamic information
