Cardiac resynchronization therapy loss diagnostics
First Claim
Patent Images
1. A system comprising:
- a processor configured to receive data generated by an implantable medical device (IMD) that is configured to deliver cardiac resynchronization therapy (CRT), wherein the received data comprises CRT data and sensed cardiac data, wherein the CRT data indicates an amount of time for which the IMD did not deliver CRT to a patient, and wherein the sensed cardiac data indicates intrinsic cardiac activity of the patient that was sensed by the IMD; and
a CRT loss diagnosis module configured to analyze the CRT data and the sensed cardiac data, and apportion the amount of time amongst a plurality of predetermined reasons for CRT loss based on the analysis.

Abstract
In some examples, an IMD provides CRT data that indicates an amount of time that CRT was not delivered by the IMD, such as the % CRT. In some examples, a CRT loss diagnosis module apportions the amount of time that CRT was not delivered amongst predetermined reasons for loss of CRT based on the CRT data and sensed cardiac data from the IMD. An external computing device may present a representation of the apportionment to a user, e.g., a clinician. The external computing device may also analyze the apportionment, and recommend programming changes for the delivery of CRT by the IMD based on the analysis.
