Abstract:
1. A system for monitoring a patient's heart, comprising: a registering unit configured to be implanted into the patient's body, said registering unit comprising a first controller in electrical communication with the patient's heart, said first controller being configured to register an electrical signal emitted by the patient's heart; and a second controller in operable communication with said first controller, said second controller being configured to receive the data from said first controller corresponding to the registered electrical signal and to compare the registered electrical signal to a baseline electrical signal emitted by the patient's heart to determine whether the patient's heart is functioning properly, wherein in comparing the registered and baseline electrical signals, said second controller is configured to generate a template of an intracardiac electrogram for each of the registered electrical signal and a baseline electrical signal and to compare the templates to determine whether the patient's heart is functioning properly, wherein said second controller is configured to determine whether a predetermined critical match-percent threshold has been exceeded based on a comparison of the templates for the registered electrical signal and the baseline electrical signal, wherein the critical match-percent threshold comprises at least 70% correlation between the templates for the registered electrical signal and the baseline electrical signal, and wherein a critical-match percent threshold less than 70% indicates that the heart is not functioning properly.
