Phrenic nerve stimulation detection with posture sensing

A system, comprising:

• an implantable medical device (IMD) for implantation in a patient, the IMD including:
• a posture sensor;
• a pace-induced phrenic nerve stimulation (PS) sensor;
• a memory;
• and
• a controller, wherein the controller is operably connected to the posture sensor to detect posture and the PS sensor to detect phrenic nerve stimulation;
• wherein the controller is configured to:
• receive a trigger for conducting a PS search;
• conduct the PS search in response to the trigger, wherein the PS search conducted by the controller includes:
• measuring a posture of the patient using the posture sensor;
• searching for PS using the PS sensor while the patient is in the measured posture and obtaining a PS result from the PS search for the measured posture;
• and
• recording in the memory both the PS result and the measured posture.
