1. An implantable medical device for monitoring an implantable biological cardiac pacemaker implanted in a heart, the device comprising:
- a first sensing system for detecting a first cardiac signal at a first location in the heart wherein the first cardiac signal is a near-field signal;
a second sensing system for detecting a second cardiac signal at a second location in the heart wherein the second cardiac signal is a far-field signal; and
a processor unit configured to compare information derived from the first cardiac signal and the second cardiac signal with at least one template cardiac signal indicative of a specific location of the implantable biological pacemaker within a heart and to determine if a cardiac depolarization from one location originated in a location of the implantable biological cardiac pacemaker or in a second location near the implantable biological cardiac pacemaker based on the information derived from the first cardiac signal and the second cardiac signal, the second location selected from the group consisting of a pacing lead site, a native pacemaker site, and an ectopic site.

Abstract
A method for monitoring a biological cardiac pacemaker. The method may include stimulating a heart at a region selected for implantation of a biological pacemaker and sensing at least one electrical signal indicative of a cardiac depolarization originating in the region selected for implantation of the biological pacemaker. The method may further include sensing at least one subsequent electrical signal produced by the heart and determining if the subsequent electrical signal originated in the region selected for the biological pacemaker or another region of the heart.
