ABSTRACT:
A computer controlled method and apparatus for displaying an electrocardiograph utilizes a computer to store and display multiple channels of an ECG signal and to develop an AVSEP and arrhythmic display. A video ECG signal is stored in memory and the R waves of the ECG complexes are detected to form an R wave pulse train. Intervals of ECG memory are displayed from adresses representing a few cycles of the ECG signal. The display of the ECG signal is triggered by a corresponding R pulse train which is stored in an address which is offset sufficiently from the address of the ECG signal so that the entire ECG complex is displayed. The method and apparatus has the option wherein the display may be switched from a time moving scan display mode to a time stationary display mode over a fixed or variable interval of scanned ECG signals.
