1. A system, comprising:

  • an implantable physiological data monitor, configured to monitor one or more physiological data parameters;

    a processor, coupled to the implantable physiological data monitor, the processor configured to,detect an episode beginning condition using a first physiological data parameter monitored by the implantable physiological data monitor, wherein the episode beginning condition is indicative of beginning of a present pathological episode; and

    detect an episode ending condition monitored by the implantable physiological data monitor, wherein the episode ending condition is indicative of the ending of the present pathological episode;

    a rolling memory buffer configured to continually store a fixed segment of a second physiological data parameter monitored by the implantable physiological data monitor;

    a static memory buffer configured to store a time segment of a third physiological data parameter monitored by the implantable physiological data monitor based on a triggering event associated with the detecting of the episode ending condition; and

    a memory configured to store data retained in the static memory buffer and associate the data retained in the static memory with the data retained in the rolling memory buffer for later use by the processor or for output to an external device.
