Abstract
A method and medical device for determining sensing vectors that includes sensing cardiac signals from a plurality of electrodes, the plurality of electrodes forming a plurality of sensing vectors, setting a blanking period and a blanking period adjustment window for the plurality of sensing vectors in response to the sensed cardiac signals, determining first signal differences during the blanking period adjustment window, and adjusting the blanking period in response to the determined first signal differences.
Claims21
A method of determining sensing vectors in a medical device, comprising:
- sensing cardiac signals from a plurality of electrodes, the plurality of electrodes forming a plurality of sensing vectors;
- setting a blanking period and a blanking period adjustment window for the plurality of sensing vectors in response to the sensed cardiac signals;
- determining first signal differences during the blanking period adjustment window;
- and
- adjusting the blanking period in response to the determined first signal differences.
A medical device for determining sensing vectors, comprising:
- a plurality of electrodes capable of forming a plurality of sensing vectors for sensing cardiac signals;
- and
- a processor configured to sense cardiac signals from the plurality of electrodes, set a blanking period and a blanking period adjustment window for the plurality of sensing vectors, determine first signal differences during the blanking period adjustment window, and adjust the blanking period in response to the determined first signal differences.
