1. A method implemented using an implantable cardioverter-defibrillator (ICD), comprising:
- detecting a cardiac tachyarrhythmia of a patient using the ICD;
delivering a defibrillation therapy to treat the tachyarrhythmia using the ICD;
if the defibrillation therapy fails to terminate the tachyarrhythmia, temporarily disabling the ICD from delivering defibrillation therapy at least for a time during which cardiopulmonary resuscitation (CPR) is administered to the patient;
detecting CPR compressions using the ICD; and
enabling the ICD to deliver defibrillation therapy in response to termination of CPR.

Abstract
Systems and methods provide for coordinated cardiac pacing with delivery of cardiopulmonary resuscitation (CPR) to a patient. Managing cardiac pacing in a patient during a cardiac arrhythmia involves detecting a cardiac arrhythmia using a patient implantable medical device, prompting a cardiopulmonary resuscitation compression, and delivering, using the patient implantable medical device, a pacing pulse to a heart chamber in coordination with the compression prompt.

10. A medical device, comprising:
-
an implantable cardioverter-defibrillator (ICD) comprising a compression detector configured to detect cardiopulmonary resuscitation (CPR) compressions; and a controller of the ICD configured to detect a cardiac tachyarrhythmia of a patient and deliver defibrillation therapy to treat the tachyarrhythmia, the controller, in response to the defibrillation therapy failing to terminate the tachyarrhythmia, configured to temporarily disable the ICD from delivering defibrillation therapy at least for a time during which CPR is administered to the patient in response to the compression detector detecting CPR compressions, the controller configured to enable the ICD to deliver defibrillation therapy in response to termination of CPR. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
