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 anda 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, before beginning delivery of a currently configured ATP therapy in response to the detected tachyarrhythmia episode, estimate a cumulative subject-specific currently-configured ATP therapy efficacy, and wherein the controller is configured to;
compare the cumulative subject-specific efficacy to a physiological condition specific efficacy threshold determined using a patient population; and
alter the delivery regimen of the ATP therapy when the cumulative subject-specific efficacy is less than the physiological condition-specific efficacy threshold.

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.

21. 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); before beginning delivery of the currently configured ATP therapy in response to the detected tachyarrhythmia episode, estimating an efficacy for the subject of an ATP therapy currently configured in the medical device; comparing the estimated efficacy to a physiological condition-specific threshold value, wherein the efficacy threshold value is statistically determined using a patient population; 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 (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. 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, before beginning delivery of the currently configured ATP therapy in response to the detected tachyarrhythmia episode, estimating an efficacy for the subject of an ATP therapy currently configured in the medical device; means for comparing the estimated efficacy to a physiological condition-specific threshold value wherein the efficacy threshold value is statistically determined using a patient population; and means for altering a delivery regimen of the currently configured ATP therapy when the estimated efficacy of the ATP therapy is deemed insufficient.
