摘要：
A method and system of detecting phrenic nerve stimulation in a patient that includes detecting an activation event, obtaining a heart sound signal of a patient from an implanted heart sound sensor, determining that an electrical stimulation has been applied to the patient, in response to detecting the activation event, monitoring a portion of the heart sound signal, the portion defined by a predetermined window after the application of the electrical stimulation, and determining whether phrenic nerve stimulation occurred based on the portion of the heart sound signal.
