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.

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.

48. The method of claim 47, 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.
