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 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 infer a likelihood of an occurrence of past cardiac arrhythmia 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.

2. The device of claim 1 , wherein the computing device is a server.

3. The device of claim 1 , wherein the computing device is a smartphone.

4. The device of claim 2 , wherein the computing device communicates with the transmitter through a smartphone intermediary.

5. The device of claim 1 , wherein the report comprises indications for the presence of atrial fibrillation.

6. The device of claim 5 , wherein the indications for the presence of atrial fibrillation comprise detecting at least 1000 beats.

7. The 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.

8. The device of claim 1 , wherein the circuit is further configured to estimate a signal amplitude from the cardiac signals and the transmitter is further configured to transmit the signal amplitude to the computing device.

9. The device of claim 1 , wherein the circuit is further configured to estimate a noise level from the cardiac signals and the transmitter is further configured to transmit the noise level to the computing device.

10. The device of claim 1 , wherein the circuit is configured to collect a secondary signal and transmit the secondary signal to the computing device.

11. The device of claim 10 , wherein the secondary signal is accelerometer data.

12. The device of claim 10 , wherein the secondary signal is electrode contact quality data.
