Cardiac Waveform Template Creation, Maintenance and Use
First Claim
1. A method of determining a cardiac pacing response to a cardiac pacing pulse, comprising:
- delivering the pacing pulse during a cardiac cycledetecting a cardiac waveform after delivery of the pacing pulse during the cardiac cycle;
determining if one or more features of the cardiac waveform fall within one or more target regions, respectively, each target region having at least a time dimension and an amplitude dimension; and
determining the cardiac pacing response based on whether the cardiac waveform features fall within the target regions; and
generating an output indicating the cardiac pacing response.

Abstract
The present disclosure describes methods and systems for creating, adjusting, and using cardiac waveform morphology templates. The morphology templates include target regions associated with features of cardiac waveforms. The target regions may be adjusted based on relationships between the target regions and features of detected cardiac waveforms associated with the target regions. The templates may be used to analyze cardiac waveforms to classify or monitor various waveform morphologies. Templates may be created or eliminated based on a frequency of use. According to one approach, template creation involves providing target regions defined by one or more characteristics. The target regions are adjusted based on detected cardiac waveform features having similar characteristics. A template may be created using the target regions adjusted by this process.
