ABSTRACT:
A pacemaker system and method for predicting cardiac allograft rejection noninvasively through the analysis of the T-wave amplitudes of evoked heartbeats. A pacemaker suitable for detecting the T-wave portions of heartbeat signals, such as the Rhythmyx pacemaker, is utilized for providing T-wave information, preferably the amplitude of the T-wave, which information is analyzed for determining a trend indicative of rejection. A decrease, or diminution of evoked T-wave amplitude indicates rejection, and can be used for appropriate follow-up treatment.
