US Patent 7756573 Implantable medical device diagnostic data acquisition and storage

A method carried out by a therapeutic implantable medical device includes detecting a plurality of physiologic episodes of interest, recording a single set of diagnostic data indicative of physiologic activity, determining that the single set of diagnostic data corresponds in time with at least two physiologic episodes, and associating the single set of diagnostic data with the least two of the plurality of physiologic episodes. As such, requests for diagnostic data associated with any of the at least two of the plurality of physiologic episodes are satisfied with diagnostic data from the single set of recorded diagnostic data.
