Patent ID: 8229559

Claim:
A system comprising: an episode classification module that: receives electrogram waveforms (EGMs) from N implantable medical devices (IMDs), wherein N is an integer greater than 1; determines whether the EGMs are associated with one or more deliveries of therapy by the N IMDs; analyzes at least some of the EGMs; and determines whether the one or more deliveries or non-deliveries of therapy by the IMDs in response to rhythms included in the EGMs were appropriate based on the analysis; and a data retrieval module that: receives a comparison request from a computing device, via a network, the comparison request indicating at least two groups of the N IMDs and a type of comparison to be made between the at least two groups; and provides to the computing device via the network, in response to the comparison request, data for presentation of a comparison between the at least two groups on the computing device, wherein the data indicates, for each of the groups, at least one of how many of the one or more deliveries or non-deliveries of therapy were appropriate, or how many of the one or more deliveries or non-deliveries of therapy were inappropriate.
