SYSTEM AND METHOD FOR HEART MONITORING
First Claim
1. A method of monitoring a transplanted heart, comprising:
- (a) during a first data collection session occurring at a reference time, registering an electrical signal from a patient'"'"'s heart, the electrical signal configured as a first series of waveforms;
(b) generating from the first series of waveforms, a reference waveform representative of the average characteristics of the waveforms collected during the first data collection session;
(c) during a subsequent data session occurring at a time subsequent to the reference time, registering an electrical signal from a patient'"'"'s heart, the electrical signal configured as a second series of waveforms;
(d) generating from the second series of waveforms, a registered waveform representative of the average characteristics of the waveforms collected during the subsequent data collection session; and
(e) comparing the registered waveform to the reference waveform to determine whether the heart is functioning properly.

Abstract
The present invention provides systems and methods for monitoring a heart. According to one embodiment, the system includes an implantable registering unit for registering an electrical signal from the heart. The system includes a local data unit in operable communication with registering unit. The local data unit may be placed in communication with a computer, which may be at a location remote from the local data unit. The computer is adapted to receive the data from the local data unit corresponding to the registered electrical signal and to compare the registered electrical signal to a reference electrical signal to determine whether the heart is functioning properly.
