Abstract

The present disclosure relates to a wearable monitor device and methods and systems for using such a device. In certain embodiments, the wearable monitor records cardiac data from a mammal and extracts particular features of interest. These features are then transmitted and used to provide health-related information about the mammal.

First claim

What is claimed is:

1. A method of monitoring the physiological data of a patient using a wearable monitor, comprising:
providing a wearable monitor configured to contact the skin of the patient, the wearable monitor comprising a hardware processer within an assembly, the assembly configured to detect a cardiac signal;
within the hardware processor, continuously collecting the cardiac signal from the patient, the hardware processor configured to use a machine-learned model to extract a machine-learned output from the cardiac signal or a derived signal therefrom, the machine-learned output comprising less data than the cardiac signal; and
wherein the wearable monitor is configured to wirelessly transmit the machine-learned output to a computing system, the computing system configured to analyze the machine-learned output to infer a likelihood of a cardiac arrhythmia originating in the past.

2. The method of claim 1 , wherein transmitting the machine-learned output consumes less battery power than transmitting the cardiac signal.

3. The method of claim 1 , wherein the cardiac signal comprises an electrocardiogram signal.

4. The method of claim 1 , wherein the cardiac signal comprises a photoplethysmography signal.

5. The method of claim 1 , wherein the wearable monitor comprises an electrode.

6. The method of claim 5 , wherein the wearable monitor comprises a plurality of electrodes.

7. The method of claim 1 , wherein the wearable monitor comprises a chest strap.

8. The method of claim 1 , wherein the wearable monitor comprises a wrist-worn watch.

9. The method of claim 1 , wherein the wearable monitor comprises a housing and a plurality of wings extending from the housing, the wings configured to adhere to the skin of the patient.

10. The method of claim 1 , wherein the computing system is remote from the wearable monitor.

11. The method of claim 1 , further comprising collecting secondary physiological data.

12. The method of claim 11 , wherein the secondary physiological data comprises motion data collected by an accelerometer.

13. The method of claim 1 , further comprising algorithmically comparing the secondary physiological data with the cardiac signal.

14. The method of claim 1 , wherein the secondary physiological data comprises electrode contact quality data.

15. The method of claim 1 , wherein the computing system comprises a gateway.

16. The method of claim 1 , further comprising generating a report, the report comprising an indication of the likelihood of an occurrence of cardiac arrhythmia.

17. The method of claim 1 , further comprising calculating atrial fibrillation burden.

18. The method of claim 17 , wherein the atrial fibrillation burden comprises an amount of time spent in atrial fibrillation by the patient.

19. The method of claim 1 , further comprising estimating a noise level from the cardiac signal.

20. The method of claim 1 , wherein the wearable monitor is configured to be worn for more than 7 days.
