Method and apparatus for beat alignment and comparison
First Claim
1. A method of analyzing cardiac events using a template having a template data set and template parameters, the method comprising:
- capturing a signal using electrodes implanted in a patient'"'"'s torso;
configuring the captured signal in accordance with the template parameters, the template parameters including identification of an amplitude peak as a fiducial point and start and end points surrounding the fiducial point;
aligning the template data set with the configured captured signal using the fiducial point; and
comparing the aligned template data set to the configured captured signal, including comparing the fiducial point identified in the configured captured signal to the fiducial point of the template data set.

Abstract
Methods of using a template having a template data set and template parameters to provide improved alignment of captured cardiac signal data to a stored template. More particularly, in an illustrative method, a captured cardiac signal is first configured using template parameters for a stored template. Then, once configured, the captured cardiac signal is then compared to the stored template. Other embodiments include implantable cardiac treatment devices including operational circuitry configured to perform the illustrative method. In a further embodiment, more than one stored templates may be used. Each template can have independently constructed parameters, such that a single captured cardiac signal may be configured using first parameters for comparison to a first template, and using second parameters for comparison to a second template.
