Abstract :
Paced epicardial electrograms from heart transplants were recorded via implanted telemetric pacemakers. Signals were processed automatically and extracted parameters from the ventricular evoked response are compared to the degree of acute rejection according to histological findings from endomyocardial biopsy. Statistical analysis and an estimation of the diagnostic quality of this noninvasive method for detection of acute cardiac rejection are presented
