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 tachyarrhythmia events, the one or more templates associated in memory with a therapy to treat tachyarrhythmia events;
detecting a cardiac waveform;
matching a particular template of the one or more templates with the cardiac waveform;
delivering the therapy based on the match between the particular template and the cardiac waveform; and
determining whether the therapy was unsatisfactory in terminating an arrhythmia associated with the particular template and, if the therapy is determined unsatisfactory, eliminating the therapy as an option for treating a subsequent tachyarrhythmia event associated in memory with the particular template and associating in memory the particular template with a new therapy.

Abstract
Cardiac treatment methods and devices providing templates representative of past tachyarrhythmia 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 tachyarrhythmia 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.

17. 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; therapy delivery circuitry configured to deliver one or more therapies to treat tachyarrhythmia events; and a template processor and memory coupled to the detector system and the cardiac therapy system, the template processor and memory configured to store one or more templates representative of one or more of a patient'"'"'s past tachyarrhythmia events, the one or more templates associated in memory with the one or more therapies, match a particular template of the one or more templates with the cardiac waveform, facilitate delivery of a therapy of the one or more therapies by the therapy delivery circuitry based on the match between the particular template and the cardiac waveform, determine whether the therapy was satisfactory in terminating an arrhythmia associated with the particular template and if the therapy is determined unsatisfactory, eliminate the therapy as an option for treating a subsequent tachyarrhythmia event associated with the particular template and associate the particular template with a new therapy. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
