In review mode of some cardiovascular recording systems it is not possible to zoom into a particular area of the waveform signal. The user cannot examine a particular area of the signal without modifying the signal display properties. Up to now, the display of signals can only be enlarged by changing the display properties of the waveform signals itself.
