Abstract
A medical device is configured to sense a cardiac signal, determine a monitoring metric representative of activity of at least one heart chamber from the sensed cardiac signal, and determine that the monitoring metric meets expected rhythm criteria. The medical device may enable a monitoring feature of the medical device that is based on processing and analysis of the cardiac signal in response to the monitoring metric meeting the expected rhythm criteria.
Claims30
A medical device comprising:
- a first sensing circuit configured to sense a first cardiac signal;
- and
- a control circuit configured to:
- determine a monitoring metric representative of activity of at least one heart chamber from the first cardiac signal;
- determine if the monitoring metric meets expected rhythm criteria by determining if the monitoring metric meets atrioventricular conduction criteria;
- in response to determining that the monitoring metric meets the atrioventricular conduction criteria:
- determine that the first cardiac signal is reliable for use by a monitoring feature of the medical device;
- and
- enable at least one monitoring feature of the medical device that is based on processing and analysis of the first cardiac signal by at least enabling an atrioventricular block monitoring feature;
- or
- in response to determining that the monitoring metric does not meet the atrioventricular conduction criteria:
- determine that the first cardiac signal is not reliable for use by a monitoring feature of the medical device;
- and
- disable at least one monitoring feature of the medical device by at least disabling the atrioventricular block monitoring feature.

A non-transitory, computer-readable storage medium comprising a set of instructions which, when executed by a control circuit of a medical device, cause the medical device to:
- sense a cardiac signal
- determine a monitoring metric representative of activity of at least one heart chamber from the cardiac signal;
- determine if the monitoring metric meets expected rhythm criteria by determining if the monitoring metric meets atrioventricular conduction criteria;
- and
- in response to determining that the monitoring metric meets atrioventricular conduction criteria:
- determine that the first cardiac signal is reliable for use by a monitoring feature of the medical device;
- and
- enable at least one monitoring feature of the medical device that is based on processing and analysis of the first cardiac signal by at least enabling an atrioventricular block monitoring feature;
- and
- in response to determining that the monitoring metric does not meet the atrioventricular conduction criteria:
- determine that the first cardiac signal is not reliable for use by a monitoring feature of the medical device;
- and
- disable at least one monitoring feature of the medical device by at least disabling the atrioventricular block monitoring feature.
