Assignee: MEDTRONIC, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 19:
20. A non-transitory computer-readable storage medium comprising instructions that, when executed by processing circuitry, cause the processing circuitry to:
determine that an asystole detection criterion is satisfied based on not identifying a cardiac depolarization in a cardiac electrogram sensed by a medical device during a time interval;
determine, based on the determination that the asystole detection is satisfied, that one or more false asystole detection criteria are satisfied based on the cardiac electrogram signal; and
withhold an indication of an asystole episode for the patient based on a determination that at least one of the one or more false asystole detection criteria is satisfied,
wherein the one or more false asystole detection criteria comprises a reduced amplitude threshold criterion for detecting cardiac depolarizations in the cardiac electrogram,
wherein, to determine that the reduced amplitude threshold criterion is satisfied, the instructions cause the processing circuitry to:
identify a plurality of cardiac depolarizations occurring in the cardiac electrogram preceding the time interval;
determine an amplitude for each cardiac depolarization of the plurality of identified cardiac depolarizations; and
determine a reduced amplitude threshold based on the determined amplitudes of the plurality of identified cardiac depolarizations.
