Storage of data for evaluation of lead integrity
First Claim
1. A system comprising:
- a sensing module that monitors a signal indicative of cardiac contractions;
a processor that detects a first high rate non-sustained episode based on the signal sensed by the sensing module and activates a data storage operation for storing data associated with high rate non-sustained episodes in response to detecting the first episode; and
a memory that stores data associated with the first episode in response to the processor activating the data storage operation, wherein the processor detects a lead integrity condition based on the signal sensed by the sensing module and determines whether the memory contains data associated with a predetermined number of high rate non-sustained episodes, and wherein the processor determines that the memory contains data associated with the predetermined number of high rate non-sustained episodes, turns off the data storage operation in response to the determination, and prevents data stored in the memory from being overwritten until the data is accessed for analysis.

Abstract
In general, the disclosure describes techniques for storing data corresponding to sensed high-rate non-sustained episodes that occur close in time to detection of a lead integrity condition. A method comprises detecting a first high-rate non-sustained episode, activating a data storage operation for storing data associated with high rate non-sustained episodes in response to detecting the first episode, and storing data associated with the first episode in an episode log in response to activating the data storage operation. Another method comprises detecting a lead integrity condition, and activating a data storage operation for storing data associated with high rate non-sustained episodes in response to detecting the condition.
