Cardiac tachyarrhythmia therapy selection based on patient response information
First Claim
1. A method, comprising:
- providing one or more templates representative of one or more of a patient'"'"'s past tachyarrythmia events, each of the templates associated with a therapy to treat tachyarrythmia events;
detecting a cardiac waveform; and
if the cardiac waveform corresponds to a particular template of the one or more templates, determining if a previous therapy associated with the particular template was satisfactory in terminating a past tachyarrhythmia event associated with the particular template, and if determined satisfactory, delivering the previous therapy, and if determined unsatisfactory, eliminating the previous therapy as an option for treating a subsequent tachyarrhythmia event associated with the particular template.

Abstract
Cardiac treatment methods and devices providing templates representative of past tachyarrythmia events, each template associated with a therapy. A cardiac waveform is detected, and if it corresponds to a particular template associated with a previous therapy that was satisfactory in terminating a past event, the previous therapy is delivered again. If unsatisfactory, the previous therapy is eliminated as an option. If, for example, the previous therapy was an antitachycardia pacing therapy unsatisfactory in terminating the past tachyarrythmia event, delivery of the antitachycardia pacing therapy is eliminated as an option. Instead of ATP therapy, one or more of a cardioversion, defibrillation, or alternate anti-tachycardia pacing therapy may be associated with the particular template. Cardiac waveforms and templates may correspond in terms of one or more of morphology, timing, drug regimen, medication, neural activity, patient activity, hemodynamic status, cardiac tissue impedance, transthoracic impedance, or other information corresponding to the episode.

22. A method, comprising:
-
providing one or more templates representative of one or more of a patient'"'"'s past tachyarrythmia events, each of the templates associated with a therapy delivered to treat a past tachyarrythmia event, the one or more templates comprising a low-rate template;
detecting a cardiac waveform;
determining that the cardiac waveform is indicative of a high-rate tachyarrythmia event having one or both of a morphology and timing corresponding to the low-rate template; and
determining if the delivered therapy associated with the low-rate template was satisfactory in terminating the past tachyarrythmia event associated with the low-rate template, and if determined satisfactory, delivering the therapy associated with the low-rate template to treat the high-rate tachyarrythmia event. - View Dependent Claims (23)

24. A medical system, comprising:
-
a cardiac therapy system configured to deliver a cardiac therapy to a patient;
a detector system configured to detect a cardiac waveform associated with a tachyarrhythmia; and
a template processor coupled to the detector system and the cardiac therapy system, the template processor configured to provide one or more templates representative of one or more of a patient'"'"'s past tachyarrythmia events, each of the templates associated with a therapy to treat tachyarrythmia events, and, if the cardiac waveform corresponds to a particular template of the one or more templates, the template processor configured to determine if a previous therapy associated with the particular template was satisfactory in terminating a past tachyarrhythmia event corresponding to the particular template, and if determined satisfactory, prompt the cardiac therapy system to deliver the previous therapy, and if determined unsatisfactory, eliminate the previous therapy as an option for treating a subsequent tachyarrhythmia event associated with the particular template, and prompt the cardiac therapy system to deliver a different therapy. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A cardiac device, comprising:
-
means for providing one or more templates representative of one or more of a patient'"'"'s past tachyarrythmia events, each of the templates associated with a therapy to treat tachyarrythmia events;
means for detecting a cardiac waveform;
means for determining if a previous therapy associated with a particular template of the one or more templates was satisfactory in terminating a past tachyarrhythmia event associated with the particular template if the cardiac waveform corresponds to the particular template; and
means for eliminating the previous therapy as an option for treating a subsequent tachyarrhythmia event associated with the particular template if the previous therapy was determined unsatisfactory.
