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.
