Method and System for Triggering an Implantable Medical Device for Risk Stratification Measurements
First Claim
1. An implantable medical device comprising a sensor, a hermetically sealed enclosure, and memory disposed within the hermetically sealed enclosure, wherein the device is programmed to identify the presence of at least one of a plurality of risk stratification measurement triggers and to store a physiological signal sensed by the sensor in response to identification of the at least one risk stratification measurement trigger.

Abstract
A method and system for triggering an implantable medical device for risk stratification measurements is disclosed. An implantable medical device having a hermetically sealed enclosure and memory disposed within the hermetically sealed enclosure. The device is programmed to record a physiological signal in response to at least one of a plurality of risk stratification measurement triggers. The stored signal is useful for implementing a variety of risk stratification for sudden cardiac death techniques.
