Abstract
An implantable medical device (IMD) and method are provided. The IMD includes a sensing channel configured to obtain biological signals indicative of biological behavior of an anatomy of interest over a period of time. The biological behavior has a feature of interest that repeats over time. The biological signals have clinically relevant (CR) segments that include information related to the feature of interest. The biological signals have non-clinically relevant (NCR) segments that do not include information related to the feature of interest. At least one of circuitry or a processor are configured to compare the biological signals to an amplitude window to distinguish the CR segments from the NCR segments, save to memory the CR segments and delete the NCR segments, save to memory time information indicative of a duration of the NCR segments that were deleted and to form a lossy compressed data set for the biological signals.
