METHOD AND APPARATUS FOR ADJUSTING CONTROL PARAMETERS FOR CARDIAC EVENT SENSING

A medical device includes a motion sensor configured to produce a motion signal and a control circuit configured to set sensing control parameters and sense atrial events from the motion signal during ventricular cycles according to the sensing control parameters. In some examples, the control circu...

Zusammenfassung:A medical device includes a motion sensor configured to produce a motion signal and a control circuit configured to set sensing control parameters and sense atrial events from the motion signal during ventricular cycles according to the sensing control parameters. In some examples, the control circuit is configured to determine a feature of the motion signal for at least some ventricular cycles, determine a metric of the motion signal based on the determined features, and adjust at least one of the sensing control parameters based on the metric.
