Therapy delivery for identified tachyarrhythmia episode types
First Claim
1. A cardiac system, comprising:
- an implantable sensing system configured to sense first electrogram signals during a first period of time and to sense second electrogram signals during a second period of time;
a tachyarrhythmia detector configured to detect intrinsic tachyarrhythmia episodes using the first electrogram signals and to detect an induced tachyarrhythmia episode using the second electrogram signals;
a data processor configured to;
identify intrinsic tachyarrhythmia episode types based on a comparison of morphological characteristics extracted from the first electrogram signals with morphological characteristics extracted from the second electrogram signals of the induced tachyarrhythmia episode that determines a similarity between the induced tachyarrhythmia episode and at least one intrinsic tachyarrhythmia episode type;
determine a tachyarrhythmia burden for each of the identified intrinsic tachyarrhythmia episode types; and
rank each of the identified intrinsic tachyarrhythmia episode types based on each of the associated tachyarrhythmia burdens; and
a display configured to present information related to the similarity between the induced tachyarrhythmia episode and the at least one intrinsic tachyarrhythmia episode type.

Abstract
Methods and systems for identifying tachyarrhythmia episode types and delivering therapy to mitigate the identified tachyarrhythmia episode types are described. Electrogram signals of cardiac activity are sensed and stored by an implantable cardiac device. Tachyarrhythmia episodes are detected and tachyarrhythmia episode types are identified based on characteristics of the electrogram signals. In preparation for performing ablation, a tachyarrhythmia episode is induced. The features of the induced tachyarrhythmia episode are compared to characteristics of the identified episode types. A similarity between the induced tachyarrhythmia episode and at least one of the episode types identified from the stored electrogram signals is indicated to facilitate performing the ablation.
