Abstract

Cardiac resynchronization therapy (CRT) performance data for a number of patients in which an implantable medical device (IMD) is implanted is aggregated and reports of the aggregated data are generated, e.g., for review by organizations or individual clinicians treating the patients. In one example, a method includes collecting CRT performance data correlated to cardiac rhythm event data for a first group of patients in which an IMD configured to deliver CRT is implanted, aggregating, with a computing device, the CRT performance data correlated to the cardiac rhythm event data for a second group of patients from among the first group of patients, and generating, with the computing device, a report comprising the aggregation of the CRT performance data correlated to the cardiac rhythm event data for the second group of patients.
