Post processing method and apparatus for reversibly converting an erase bar ECG waveform display to a scrolling ECG waveform display

摘要

An apparatus and post-processing method for reversibly converting an existing electrocardiograph (ECG) erase bar waveform display to a scrolling waveform display. This conversion is accomplished by swapping the positions of the portions of the waveform that are displayed to the right and left of the erase bar in an erase bar waveform display each time a new heartbeat data point is displayed. The swapping function is accomplished by delaying the display of the data points to the right of the erase bar by a time period x and by delaying the display of data points to the left of the erase by x plus the amount of time required to scan an entire row. x is the amount of time required to scan all of the data points displayed to the right of the erase bar on the erase bar waveform display.
