    摘要： Methods and systems involve classifying the cardiac response to pacing using a multi-channel approach. Multiple cardiac response signals are sensed via multiple sense channels. Each sense channel comprises a distinct combination of electrodes and sensing circuitry. The cardiac response to the pacing pulse is classified based on the morphology of the cardiac response signals. Classifying the cardiac response involves discriminating between capture, fusion, non-capture, and non-capture with intrinsic activity.

    摘要： Systems and methods involve determination of CRT parameters using a number of CRT optimization processes. Each CRT optimization process attempts to return recommended parameters. The CRT parameters are determined based on the recommended parameters returned by one or more of the CRT optimization processes. The CRT optimization processes may be sequentially implemented and the CRT parameters may be determined based on the recommended parameters returned by a first CRT optimization process to return recommended parameters. The CRT parameters may be determined based on a combination of the recommended parameters returned. The CRT optimization processes implemented may be selected from available CRT optimization processes based on patient conditions.

    摘要： The waveform morphology of a propagated pacing response signal may be adjusted to achieve a waveform morphology that enhances cardiac pacing response determination. One or more pacing intervals may be adjusted to achieve at least one cardiac pacing response waveform morphology that enhances determination of the cardiac pacing response. The heart is paced using the one or more adjusted pacing intervals and the cardiac response to the pacing is determined. The one or more adjusted pacing intervals may include an atrioventricular pacing delay, an interatrial pacing delay, an interventricular pacing delay, or other inter-chamber or inter-site pacing delays. Adjusting the one or more pacing intervals may be used to increase a difference between a first waveform morphology associated with multi-chamber capture and a second waveform morphology associated with single chamber capture.

    摘要： Methods and devices for classifying a cardiac response to pacing involve establishing a retriggerable cardiac response classification window. A first cardiac response classification window is established subsequent to delivery of a pacing pulse. A cardiac signal following the pacing stimulation is sensed in the first classification window. A second cardiac response classification may be triggered if a trigger characteristic is detected in the first classification window. The cardiac signal is sensed in the second classification window if the second classification window is established. The cardiac response to the pacing stimulation is determined based on characteristics of the cardiac signal. The cardiac response may be determined to be one of a captured response, a non-captured response; a non-captured response added to an intrinsic beat, and a fusion/pseudofusion beat, for example.
