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.

Abstract
Monitoring physiological parameter using an implantable physiological monitor in order to detect a condition predictive of a possible future pathological episode and collecting additional physiological data associated with the condition predictive of a possible future pathological episode. Monitoring another physiological parameter in order to detect a condition indicative of the beginning of a present pathological episode and collecting additional pathological data in response to the condition. Determining that the condition predictive of a future episode and the condition indicative of a present episode are associated and, in response thereto, storing all the collected physiological data.

11. A method, comprising:
-
monitoring first physiological data using an implantable physiological monitor; using the first physiological data, detecting an episode beginning condition indicative of a beginning of a present pathological episode; responding to detecting the episode beginning condition by collecting second physiological data associated with the detecting the episode beginning condition; detecting an episode ending condition indicative of the ending of the present pathological episode; responding to detecting the episode ending condition by collecting third physiological data associated with the detecting of the episode ending condition, wherein collecting the third physiological data is triggered after a specified delay beyond a time the episode ending condition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
