1. An ambulatory medical device configured to be worn on a body of a patient, the ambulatory medical device comprising:
at least one electrocardiogram (ECG) electrode configured to sense cardiac activity of the patient;
at least one acoustic sensor configured to detect one or more sounds indicative of a state of health of the patient;
at least one motion sensor configured to detect motion of the patient; and
at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one motion sensor and configured to
receive at least one ECG signal corresponding to the sensed cardiac activity of the patient from the at least one ECG electrode,
receive at least one acoustic signal corresponding to the one or more sounds indicative of the state of health of the patient from the at least one acoustic sensor,
receive at least one motion signal corresponding to the motion of the patient from the at least one motion sensor, and
transmit the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal to a remote system for identification of sleep apnea in the patient based on analysis of the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal, wherein the analysis includes an analysis of at least a strength of an S3 sound from the at least one acoustic signal.
