Abstract

A system and method for presenting information relating to heart data can involve operations including identifying arrhythmia events in physiological data obtained for a living being, receiving human assessments of at least a portion of the arrhythmia events, determining a measure of correlation between the human assessments and the identified events, and selectively presenting information regarding the identified events based on the measure of correlation. The operations can also include identifying atrial fibrillation events in physiological data obtained for a living being, obtaining heart rate data for the living being, and presenting information regarding the heart rate data and duration of the atrial fibrillation events together with a common time scale to pictographically represent heart rate trend with atrial fibrillation burden during a defined time period.

Claims

1. A method comprising:

obtaining a physiological signal for a living being;

performing, using a computer implemented process, a first assessment of the physiological signal over a first time period consisting of a plurality of time intervals, wherein each of the plurality of time intervals has a uniform time length;

based on performing the first assessment of the physiological signal, identifying multiple arrhythmia events of a first type and multiple arrhythmia events of a second type in the physiological signal, wherein identifying the multiple arrhythmia events of the first type and the multiple arrhythmia events of the second type comprises;

examining the physiological signal in each of the plurality of time intervals;

identifying first time intervals based on at least one arrhythmia event of the first type occurring during each of the first time intervals; and

identifying second time intervals based on at least one arrhythmia event of the second type occurring during each of the second time intervals;

obtaining heart rate data for the living being; and

pictographically presenting, using a common time scale;

the heart rate data;

indications of the identified multiple arrhythmia events of the first type; and

indications of the identified multiple arrhythmia events of the second type, wherein;

pictographically presenting the indications of the identified multiple arrhythmia events of the first type comprises pictographically presenting, on the common time scale, first markers having the uniform time length and representing the identified first time intervals; and

pictographically presenting the indications of the identified multiple arrhythmia events of the second type comprises pictographically presenting, on the common time scale, second markers having the uniform time length and representing the identified second time interval;

wherein the uniform time length is 30 seconds, 1 minute, 10 minutes, or 30 minutes.

2. The method of claim 1, further comprising pictographically presenting an indication of a maximum heart rate during a time period and a time during the time period when the maximum heart rate occurred.

3. The method of claim 1, further comprising pictographically presenting an indication of a minimum heart rate during a time period and a time during the time period when the minimum heart rate occurred.

4. The method of claim 1, further comprising:

identifying a first subset of the identified multiple arrhythmia events of the first type as urgent;

wherein pictographically presenting the indications of the identified multiple arrhythmia events of the first type comprises pictographically presenting indications of the first subset of the identified multiple arrhythmia events of the first type.

5. The method of claim 1, further comprising:

identifying a first subset of the identified multiple arrhythmia events of the first type as representative;

wherein pictographically presenting the indications of the identified multiple arrhythmia events of the first type comprises pictographically presenting the indications of the first subset of the identified multiple arrhythmia events of the first type.

6. The method of claim 1, further comprising:

receiving a second assessment of a portion of the physiological signal associated with a corresponding portion of the physiological signal;

determining that the identified multiple arrhythmia events of the first type are valid when a threshold of the identified multiple arrhythmia events of the first type match arrhythmia events of the first type identified by the second assessment; and

determining that the identified multiple arrhythmia events of the second type are valid when a threshold of the identified multiple arrhythmia events of the second type match arrhythmia events of the second type identified by the second assessment.

7. The method of claim 6, wherein obtaining the physiological signal for the living being comprises obtaining ECG data from a mobile monitoring system, and wherein the second assessment comprises requesting additional ECG data from the mobile monitoring system.
