1. A method for classifying heartbeat waveforms contained in stored ECG data comprising the steps of:
- displaying a heartbeat waveform in each of a plurality of display windows;
selecting two of the display windows;
displaying the heartbeat waveforms in the selected display windows superimposed in a compare window; and
classifying the heartbeat waveform in one of the selected windows.

Abstract
A computer controls a video display having a display screen for displaying ECG heartbeats superimposed over one another. The ECG data is collected during Holter monitoring and stored in a memory. The Holter monitor preliminarily classifies each beat to a morphology. A representative sample of each morphology is presented in a display window. Each sample can be overlaid with any other selected sample, in different colors, in a compare window having an enlarged scale from the display windows. After comparison, different morphologies can be merged and a selected beat classification can be reclassified to another morphology.
