Patent ID: 8649860

Claim:
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 predictor condition using a first physiological data parameter monitored by the implantable physiological data monitor, wherein the episode predictor condition is predictive of a possible future pathological episode; and detect an episode beginning condition using a second physiological data parameter monitored by the implantable physiological data monitor, wherein the episode beginning condition is indicative of beginning of a present pathological episode; a static memory buffer configured to store a time segment of a third physiological data parameter monitored by the implantable physiological data monitor when triggered by the detection of the episode predictor condition; a rolling memory buffer used to continually store a fixed segment of a fourth physiological data parameter monitored by the implantable physiological data monitor; and a memory configured to store data retained in the static memory buffer and the rolling memory buffer, when triggered by the detection of the episode beginning condition by the processor, for later use by the processor or for output to an external device.
