US Patent 7720535 Pacing management during cardiopulmonary resuscitation

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.
