摘要
A method and system for managing delivery of a respiration gated defibrillation shock from a subcutaneous implantable medical device (S-IMD) having one or more extra vascular electrodes. The method and system sense cardiac events of a heart. Additionally, the method and system utilize one or more processors to declare a shockable arrhythmia based on the cardiac events, obtain a respiration proxy signal indicative of respiration, track a respiration state related (RSR) characteristic from the respiration proxy signal, gate delivery of a high voltage (HV) shock based on occurrence of a respiration-gated (RG) trigger in connection with the RSR characteristic, and deliver the HV shock along a shocking vector between extra vascular electrodes based on the RG trigger to time delivering of the HV shock to occur during the select state within the respiration cycle.
