System and method for determining a probability for a person to have arrhythmia

1. A system for determining a probability of arrhythmia for a person, the system comprising:

a wearable device comprising:

means for measuring a heartbeat interval of the person; and

an accelerometer;

means for measuring an electrocardiogram of the person;

a user interface for providing information and alerts; and

a processor configured to:

detect a period of rest of the person, based on the accelerometer continuously measuring and communicating measurement data to the processor; and, only when a period of rest of the person is detected:

measure, only during the period of rest, a resting heartbeat interval of the person for a period of time;

analyze the measured resting heartbeat interval to determine a probability of having arrhythmia for the person;

generate an alert, during the period of rest, to the user interface based on the analyzed measured resting heartbeat interval, if the probability exceeds a predetermined threshold value, to alert the person to measure the electrocardiogram with the means for measuring an electrocardiogram;

analyze the measured electrocardiogram to determine if the probable arrhythmia is confirmed;

determine whether the electrocardiogram is in sync with the measured resting heartbeat interval; and

indicate the confirmed arrhythmia to the person via the user interface.

2. The system according to claim 1 , wherein the means for measuring heartbeat interval is selected from electrical measurement means, optical measurement means and ballistic measurement means.

3. The system according to claim 1 , wherein the wearable device is selected from a wristband, an ankleband, a ring and a chest belt.

4. The system according to claim 1 , wherein the means for measuring heartbeat interval is a portable computing device equipped with a camera and a processor configured to determine the heartbeat interval.

5. The system according to claim 1 , wherein at least one of the means for measuring an electrocardiogram, the processor and the user interface is arranged in a portable computing device.

6. The system according to claim 1 , wherein the processor is further configured to alert a medical professional of a confirmed arrhythmia.

7. The system according to claim 1 , wherein the period of time is from 10 seconds to 60 minutes.

8. A method using a system for determining a probability of arrhythmia for a person, comprising:

a wearable device comprising:

means for measuring a heartbeat interval of the person; and

an accelerometer;

means for measuring an electrocardiogram of the person;

a user interface for providing information and alerts; and

a processor configured to;

detect a period of rest of the person, based on the accelerometer continuously measuring and communicating measurement data to the processor; and, only when a period of rest of the person is detected:

measure, only during the period of rest, a resting heartbeat interval of the person for a period of time;

analyze the measured resting heartbeat interval to determine a probability of having arrhythmia for the person;

generate an alert, during the period of rest, to the user interface based on the analyzed measured resting heartbeat interval, if the probability exceeds a predetermined threshold value, to alert the person to measure the electrocardiogram with the means for measuring an electrocardiogram;

analyze the measured electrocardiogram to determine if the probable arrhythmia is confirmed;

determine whether the measured electrocardiogram is in sync with the measured resting heartbeat interval; and

indicate the confirmed arrhythmia to the person via the user interface, for determining if there is a need for measuring an electrocardiogram of the person,

analyzing the measured electrocardiogram to detect if probable arrhythmia is confirmed, and

creating an alert if the arrhythmia is confirmed, by giving an alert to measure an electrocardiogram if there is a probability of arrhythmia for a person, the method comprising steps of:

measuring heartbeat interval of the person for a period of time with the wearable device;

analyzing the measured heartbeat interval, with the processor of the wearable device, to determine a probability of having arrhythmia for the person; and

alerting the person to measure an electrocardiogram, with the user interface of the wearable device, if the probability exceeds a predetermined threshold value.

9. The method according to claim 8 , further comprising sending the alert to at least one of the person and a third party.

10. A method according to claim 9 , wherein the third party is a medical professional or an emergency response center.
