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.
