Abstract:
1. A method, comprising: storing one or more cardiac signal templates representative of one or more of a patient's past tachyarrhythmia episodes in memory; associating the one or more templates stored in memory with a tachyarrhythmia therapy to treat tachyarrhythmia episodes; detecting a cardiac waveform; comparing a particular template of the one or more stored templates with the cardiac waveform for a match; delivering a tachyarrhythmia therapy associated with the particular template based on the match between the particular template and the cardiac waveform; determining whether the delivered therapy associated with the particular template was unsatisfactory in terminating a tachyarrhythmia associated with the particular template; and eliminating the tachyarrhythmia therapy as an option for treating a subsequent tachyarrhythmia episode associated in memory with the particular template if the therapy is determined unsatisfactory.
