Cardiac template generation based on patient response information
First Claim
1. A processor-implemented cardiac template generation method, comprising:
- providing, patient-externally, a cardiac waveform representative of a patient'"'"'s cardiac activity comprising an arrhythmic event;
identifying, patient-externally, a portion of the cardiac waveform indicative of the arrhythmic event;
generating a cardiac template corresponding to the cardiac waveform portion; and
associating, using the processor, a therapy with the cardiac template useful for treating a subsequent arrhythmic event corresponding to the cardiac template.

Abstract
Cardiac treatment methods and devices provide for templates representative of past tachyarrhythmia events, each template associated with a therapy. Methods involve providing a cardiac waveform representative of a patient'"'"'s cardiac activity and identifying a portion that indicates an arrhythmic event. A cardiac template corresponding to the portion is generated, and a therapy is associated with the template useful for treating a subsequent arrhythmia. The waveform portion may be identified by a physician using a patient-external device to display the cardiac waveform. The template may be generated by a physician selecting the cardiac waveform, and determining if the therapy associated with the template was satisfactory and/or effective in treating the arrhythmia. Identification may involve matching the event to templates generated using cardiac waveforms other than the patient'"'"'s cardiac waveforms. The template may be generated in a patient-internal or patient-external medical device such as a programmer, and/or an advanced patient management system.
