Abstract

A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure physiological information from the subject, and at least one processor configured to process signals from the PPG sensor to determine heart rate and RR-interval (RRi) for the subject, and to determine a heart rate pattern for the subject over a period of time. The at least one processor is configured to change a sampling frequency of the PPG sensor for determining RRi in response to the determined heart rate pattern. The at least one processor is configured to reduce the sampling frequency of the PPG sensor in response to determining a pattern of heart rate below a threshold.

Claims (29)

1. A monitoring device configured to be attached to a subject, the monitoring device comprising:

a photoplethysmography (PPG) sensor configured to measure physiological information from the subject; and

at least one processor configured to process signals from the PPG sensor to:

determine heart rate and RR-interval (RRi) for the subject; and

determine a heart rate pattern for the subject over a period of time;

wherein the at least one processor is configured to change a sampling frequency of the PPG sensor to determine a statistical metric of RRi.

2. The monitoring device of claim 1 , wherein the at least one processor is configured to reduce the sampling frequency of the PPG sensor in response to determining that a pattern of heart rate is below a threshold.

3. The monitoring device of claim 2 , wherein the at least one processor is configured to reduce the sampling frequency of the PPG sensor by reducing a polling rate of an optical emitter of the PPG sensor and/or by reducing a sampling rate of an optical detector of the PPG sensor.

4. The monitoring device of claim 1 , wherein the at least one processor is further configured to change an interrogation power of the PPG sensor for determining RRi in response to the determined heart rate pattern, and to reduce the interrogation power of the PPG sensor in response to determining that a pattern of heart rate is below a threshold.

5. The monitoring device of claim 4 , wherein the at least one processor is configured to reduce the interrogation power of the PPG sensor by selecting and using a power-efficient time-domain processing method for determining RRi.

6. The monitoring device of claim 1 , further comprising at least one motion sensor configured to sense motion of the subject, wherein the processor is configured to determine an activity state of the subject by processing motion information from the at least one motion sensor, and wherein the processor is further configured to determine RRi only if the activity state is at or below a threshold.

7. The monitoring device of claim 1 , wherein the monitoring device is configured to be positioned at or within an ear of the subject.

8. The monitoring device of claim 1 , wherein the monitoring device is configured to be secured to an appendage of the subject.

9. The monitoring device of claim 1 , wherein the at least one processor is further configured to determine whether or not the subject is likely to have atrial fibrillation based on the heart rate pattern for the subject over the period of time.

10. The monitoring device of claim 9 , wherein the at least one processor is further configured to increase the sampling frequency of the PPG sensor to collect higher acuity data, and to diagnose whether or not atrial fibrillation is truly occurring using the higher acuity data.

11. A method of monitoring a subject via a monitoring device attached to the subject, wherein the monitoring device comprises a photoplethysmography (PPG) sensor and at least one processor, the method comprising:

obtaining physiological information from the subject via the PPG sensor;

processing signals from the PPG sensor via the at least one processor to determine heart rate and RR-interval (RRi) for the subject, and to determine a heart rate pattern for the subject over a period of time; and

changing, via the at least one processor, a sampling frequency of the PPG sensor to determine a statistical metric of RRi.

12. The method of claim 11 , comprising changing the sampling frequency of the PPG sensor in response to determining that a pattern of heart rate is below a threshold.

13. The method of claim 12 , wherein reducing the sampling frequency of the PPG sensor comprises reducing a polling rate of an optical emitter of the PPG sensor and/or reducing a sampling rate of an optical detector of the PPG sensor.

14. The method of claim 11 , further comprising changing an interrogation power of the PPG sensor for determining RRi in response to the determined heart rate pattern.

15. The method of claim 14 , wherein changing the interrogation power of the PPG sensor comprises reducing the interrogation power of the PPG sensor in response to determining that a pattern of heart rate is below a threshold.

16. The method of claim 15 , wherein reducing the interrogation power of the PPG sensor comprises selecting and using a power-efficient time-domain processing method for determining RRi.

17. The method of claim 11 , wherein the monitoring device further comprises at least one motion sensor configured to sense motion of the subject, and wherein the method further comprises determining, via the at least one processor, an activity state of the subject by processing motion information from the at least one motion sensor, and determining RRi only if the activity state is at or below a threshold.

18. The method of claim 11 , wherein the monitoring device is configured to be positioned at or within an ear of the subject.

19. The method of claim 11 , wherein the monitoring device is configured to be secured to an appendage of the subject.

20. The method of claim 11 , wherein processing signals from the PPG sensor via the at least one processor to determine a heart rate pattern for the subject over a period of time comprises determining whether or not the subject is likely to have atrial fibrillation.

21. The method of claim 20 , wherein changing the sampling frequency of the PPG sensor comprises increasing the sampling frequency of the PPG sensor to collect higher acuity data, and wherein the method further comprises diagnosing, via the at least one processor, whether or not atrial fibrillation is truly occurring using the higher acuity data.
