Abstract:
1. A method of operating an implantable cardiac device comprising: associating one or more target region attributes with each of a plurality of target regions, the one or more target region attributes including at least sampling rate and each target region having a location, a time dimension, and an amplitude dimension; detecting a cardiac waveform feature; adjusting at least one target region of the plurality of target regions based on a location of the detected feature of the cardiac waveform and compatibility between the attributes of the at least one target region and attributes of the waveform feature; delivering a cardiac pacing pulse during a cardiac cycle; detecting a subsequent cardiac waveform after delivery of the pacing pulse; determining a cardiac pacing response to the pacing pulse based on whether features of the subsequent cardiac waveform fall within the plurality of target regions; and adjusting a pacing energy of the cardiac device based on the cardiac pacing response.
