Abstract:
1. A method for performing and evaluating independent, off-line event sensing for collected electrograms, comprising: sensing an electrogram using an implantable medical device (IMD); the IMD determining locations of heart beats within the electrogram, resulting in a group of device-identified beat locations for the electrogram; storing the electrogram and device-identified beat locations in a memory location; retrieving, by an external computing device, the electrogram and device-identified beat locations from the memory location; after retrieving the electrogram from the memory location, determining, by the external computing device, locations of heart beats on at least a first channel of the electrogram using a multi-pass process, resulting in a group of multi-pass beat locations, wherein the multi-pass process comprises: comparing the device-identified group of beat locations to the multi-pass group of beat locations identified using the multi-pass method.
