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 data associated with multiple arrhythmia events identified, according to a computer implemented process, in a physiological signal for a living being;

receiving a human assessment of a portion of the data associated with a corresponding portion of the multiple arrhythmia events identified in the physiological signal;

determining that the multiple arrhythmia events identified in the physiological signal, including events not in the human assessed portion of the data, are valid when a threshold of the arrhythmia events identified according to the computer implemented process in the physiological signal in the human assessed portion of the data, match events identified by the human assessment of the human assessed portion of the data; and

generating information for a report to present the valid arrhythmia events for a defined period of time.

2. The method of claim 1, wherein obtaining the data associated with the multiple arrhythmia events identified according to the computer implemented process, in the physiological signal comprises obtaining ECG data.

3. The method of claim 2, wherein generating the information for the report comprises generating information for a pictographic report presenting on a common time scale heart rate trend in alignment with indications of the valid arrhythmia events.

4. The method of claim 2, wherein generating the information for the report comprises generating information for a pictographic report presenting a range of heart rates and a heart rate average for each of multiple time intervals juxtaposed with an indication of intervals of the multiple time intervals that correspond to the valid arrhythmia events.

5. The method of claim 4, further comprising providing the information over a network for displaying the report.

6. The method of claim 4, wherein generating the information for the report comprises generating information for presenting on the pictographic report an indication of a time interval of the multiple time intervals having a minimum heart rate for the multiple time intervals.

7. The method of claim 6, wherein generating the information for the report comprises generating information for presenting on the pictographic report an indication of a time interval of the multiple time intervals having a maximum heart rate for the multiple time intervals.

8. A system comprising:

a mobile monitoring system comprising a sensor to obtain physiological data from a living being, the mobile monitoring system configured to identify multiple arrhythmia events in the physiological data; and

a monitoring center in two-way communication with the mobile monitoring system via a network to obtain the physiological data, the monitoring center configured to compare the identified multiple arrhythmia events with a human assessment of a portion of the physiological data associated with a corresponding portion of the multiple arrhythmia events to determine that the multiple identified arrhythmia events, including events not in the human assessed portion of the data, are valid when a threshold of the multiple identified arrhythmia events identified by the mobile monitoring system matches events identified by the human assessment of the human assessed portion of the data, and the monitoring center further configured to output information for generation of a report to present the valid arrhythmia events with respect to a defined period of time.

9. The system of claim 8, wherein the monitoring center is further configured to provide the information over a network for displaying the report.

10. The system of claim 8, wherein the physiological data obtained by the sensor comprises ECG data.

11. The system of claim 10, wherein the multiple arrhythmia events comprise multiple atrial fibrillation events.

12. The system of claim 11, wherein the monitoring center is configured to output the information for generation of a pictographic report to present on a common time scale heart rate trend in alignment with indications of the valid arrhythmia events.

13. The system of claim 11, wherein the monitoring center is configured to output the information for generation of a pictographic report to present a range of heart rates and a heart rate average for each of multiple time intervals juxtaposed with an indication of intervals of the multiple time intervals that correspond to the valid events.

determining that the multiple arrhythmia events identified in the physiological signal, including events not in the human assessed portion of the data, are valid when a threshold of the arrhythmia events identified according to the computer implemented process in the physiological signal in the human assessed portion of the data, match events identified by the human assessment of the human assessed portion of the data; and

generating information for a report to present the valid arrhythmia events for a defined period of time.

16. The computer readable medium of claim 15, wherein obtaining the data associated with the multiple arrhythmia events identified according to the computer implemented process, in the physiological signal comprises obtaining ECG data.
