Wearable monitor with arrhythmia burden evaluation
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.
1. A wearable device for monitoring data, the device comprising:
a sensor and circuit configured to detect or derive cardiac signals from a mammal, the circuit configured to estimate a heartbeat time series from the cardiac signals;
a transmitter, the transmitter configured to transmit the heartbeat time series to a computing device, the computing device configured to determine an atrial fibrillation burden from the heartbeat time series; and
wherein the computing device is configured to provide a report, the report comprising the likelihood of the occurrence of past atrial fibrillation event.
2. The wearable device of claim 1 , wherein the atrial fibrillation burden comprises an amount of time spent in atrial fibrillation by the mammal per day.
3. The wearable device of claim 1 , wherein the atrial fibrillation burden comprises an amount of time spent in atrial fibrillation by the mammal per minute.
4. The wearable device of claim 1 , wherein the atrial fibrillation burden comprises an amount of time spent in atrial fibrillation by the mammal during a sleep period and during a wake period.
5. The wearable device of claim 1 , wherein the report comprises a histogram of atrial fibrillation burden.
6. The wearable device of claim 1 , further comprising an accelerometer, the accelerometer configured to measure movement of the mammal.
7. The wearable device of claim 6 , wherein the atrial fibrillation burden comprises an amount of time spent in atrial fibrillation during movement of the mammal.
8. The wearable device of claim 7 , wherein the movement of the mammal comprises a first degree of movement and a second degree of movement.
9. The wearable device of claim 1 , wherein the report comprises a 14 day monitoring period.
10. The wearable device of claim 1 , wherein the computing device infers a plurality of most probable cardiac rhythms by filtering the heartbeat time series according to a predetermined threshold.
11. The wearable device of claim 1 , wherein the sensor and circuit are contained within a chest strap.

a sensor and circuit configured to detect or derive cardiac signals from a mammal, the circuit configured to estimate a heartbeat time series from the cardiac signals;
a transmitter, the transmitter configured to transmit the heartbeat time series to a computing device, the computing device configured to determine an arrhythmia burden from the heartbeat time series; and
wherein the computing device is configured to provide a report, the report comprising the likelihood of the occurrence of past cardiac arrhythmia.
15. The wearable device of claim 14 , wherein the arrhythmia comprises ventricular tachycardia.
16. The wearable device of claim 14 , wherein the arrhythmia comprises supraventricular tachycardia.
17. The wearable device of claim 14 , wherein the arrhythmia comprises ectopy.
