PATIENT CHARACTERISTIC BASED ADAPTIVE ANTI-TACHY PACING PROGRAMMING
First Claim
1. A system comprising:
- a first device including;
at least one implantable sensor circuit configured to produce an electrical sensor signal related to one or more physiologic cardiovascular events of a subject;
a therapy circuit configured to provide anti-tachycardia pacing (ATP) therapy; and
a controller, communicatively coupled to the sensor circuit and the therapy circuit, the controller including;
a tachyarrhythmia detection circuit configured to detect a tachyarrhythmia episode in the subject using the electrical sensor signal, and to determine whether the tachyarrhythmia episode is of a type that is treatable with ATP; and
an efficacy circuit configured to estimate a currently configured ATP therapy efficacy for the subject, and wherein the controller is configured to alter a delivery regimen of the currently configured ATP therapy when the estimated ATP therapy efficacy is deemed insufficient.

Abstract
A system including at least one implantable sensor circuit adapted to produce an electrical sensor signal related to one or more physiologic cardiovascular events of a subject, a therapy circuit configured to provide anti-tachycardia pacing (ATP) therapy, and a controller. The controller includes a tachyarrhythmia detection circuit and an efficacy circuit. The tachyarrhythmia detection circuit is configured to detect a tachyarrhythmia episode in the subject using the electrical sensor signal, and to determine whether the tachyarrhythmia episode is of a type that is treatable with ATP. The efficacy circuit is configured to estimate an efficacy of a currently configured ATP therapy for the subject, and the controller is configured to alter a delivery regimen of the currently configured ATP therapy when the estimated ATP therapy efficacy is deemed insufficient. Other systems and methods are described.

22. A method comprising:
-
detecting a tachyarrhythmia episode in a subject using a medical device, wherein the tachyarrhythmia episode is of a type treatable with anti-tachycardia pacing (ATP); estimating an efficacy for the subject of an ATP therapy currently configured in the medical device; and altering a delivery regimen of the currently configured ATP therapy when the estimated efficacy of the ATP therapy is deemed insufficient. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A system comprising:
-
means for detecting a tachyarrhythmia episode in a subject using a medical device, wherein the tachyarrhythmia episode is of a type treatable with anti-tachycardia pacing (ATP); means for estimating an efficacy for the subject of an ATP therapy currently configured in the medical device; and means for altering a delivery regimen of the currently configured ATP therapy when the estimated efficacy of the ATP therapy is deemed insufficient.
