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. A plurality of successive heartbeats are written to the display with their R-waves aligned. As the next new heartbeat in chronological order is displayed the longest-displayed heartbeat is removed. The total number of heartbeats displayed therefore remains constant. The user can select the total number of heartbeats, between one and five, to be displayed at one time. In one mode, a heartbeat is added, and removed, during each screen refresh cycle. In another mode, the user can step the display in either reverse or forward chronological order one step at a time. A second display is provided upon which heartbeat waveforms are added at the end of a continuous ECG waveform each time a new heartbeat waveform is superimposed in the other display. The same heartbeat waveform is written to each display at the same time.
