Abstract: A method includes receiving—by a first computing system—electrocardiogram (ECG) data and metadata associated with the ECG data, where the metadata includes an initial cardiac event classification and an initial beat classification for beats occurring during a first event associated with the initial cardiac event classification. The method further includes causing the ECG data to be displayed in a user interface (UI) and receiving a command, via the UI, to change the initial beat classifications to subsequent beat classifications. The method also includes automatically modifying, by the first computing system, the initial cardiac event classification to a subsequent cardiac event classification based on the subsequent beat classifications.

Abstract: A method includes assigning a first instance of a cardiac event that occurred in a patient during a period of time to a first bucket of a first plurality of buckets based on a first measured heart rate of the patient during the first instance. A first heart rate threshold of the first bucket is less than the first measured heart rate. The method also includes determining whether the first heart rate threshold exceeds heart rate thresholds of all buckets of the plurality of buckets to which an instance of the cardiac event that occurred in the patient during the period of time is assigned, determining whether a number of instances of the cardiac event that occurred in the patient during the period of time exceeds an event threshold, and preventing the first instance of the cardiac event from being communicated for clinical review.
