Abstract

In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.

Claims (43)

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.

2. The ambulatory medical device of claim 1 , comprising a garment to be worn about a torso of the patient.

3. The ambulatory medical device of claim 2 , wherein the at least one acoustic sensor and the at least one motion sensor are mechanically coupled to the garment.

4. The ambulatory medical device of claim 1 , wherein the at least one acoustic sensor is positioned to record snoring sounds from the patient.

5. The ambulatory medical device of claim 1 , wherein the at least one motion sensor is configured to detect rising and falling of a chest of the patient.

6. The ambulatory medical device of claim 1 , wherein the at least one acoustic sensor is configured to detect rising and falling of a chest of the patient.

7. The ambulatory medical device of claim 1 , wherein the at least one motion sensor is configured to be placed on a torso or wrist of the patient.

8. The ambulatory medical device of claim 1 , further comprising a therapy delivery interface configured to provide a therapeutic shock to the patient.

9. A medical system comprising:

a server; and

a medical device comprising:

a first network interface;

at least one electrocardiogram (ECG) electrode configured to sense cardiac activity of a 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 the server via the first network interface 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;

wherein the server comprises a second network interface configured to receive the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal from the medical device.

10. The medical system of claim 9 , wherein the medical device comprises a garment to be worn about a torso of the patient.

11. The medical system of claim 10 , wherein the at least one acoustic sensor and the at least one motion sensor are mechanically coupled to the garment.

12. The medical system of claim 9 , wherein the server is configured to perform further processing with one or more of the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal.

13. The medical system of claim 9 , wherein the at least one acoustic sensor is positioned to record snoring sounds from the patient.

14. The medical system of claim 9 , wherein the at least one motion sensor is configured to detect rising and falling of a chest of the patient.

15. The medical system of claim 9 , wherein the at least one acoustic sensor is configured to detect rising and falling of a chest of the patient.

16. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform a method to identify sleep apnea in a patient, the method comprising:

receiving at least one acoustic signal corresponding to one or more sounds indicative of a state of health of the patient from at least one acoustic sensor coupled to a garment worn by the patient;

receiving at least one ECG signal corresponding to a sensed cardiac activity of the patient from at least one ECG electrode coupled to the garment worn by the patient;

receiving at least one motion signal corresponding to a motion of the patient from at least one motion sensor coupled to the garment worn by the patient; and

transmitting 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.

17. The non-transitory computer readable medium of claim 16 , wherein the method further comprises storing a record in a memory, the record being associated with the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal.

18. The non-transitory computer readable medium of claim 16 , wherein the method further comprises issuing a notification to the remote system, the notification being associated with the at least one acoustic signal, the at least one ECG signal, and the at least one motion signal.

19. The non-transitory computer readable medium of claim 16 , wherein the method further comprises, in response to identifying sleep apnea in the patient, communicating an alarm to the patient or to a caregiver of the patient.
