• a remote computing system comprising:
• a user interface (UI), a first processor, and a first computer-readable medium having a first set of computer-executable instructions embodied thereon, the first set of instructions configured to be executed by the first processor to cause the first processor to:
• after receiving electrocardiogram (ECG) data and metadata including an initial cardiac event classification and an initial beat classification for beats occurring during a first event associated with the initial cardiac event classification:
• display the ECG data in the UI;
• receive a command to change the initial beat classifications to subsequent beat classifications;
• and
• automatically modify the initial cardiac event classification to a subsequent cardiac event classification based on the subsequent beat classifications.
