ADAPTIVE EVENT STORAGE IN IMPLANTABLE DEVICE
First Claim
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 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.

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.
