How to Simulate ECG Waveforms
61
For all waveforms but VFIB and Triangle, the rate or
frequency of the waveform is adjusted through the
Frequency or Rate softkey. For some waveforms, there
are more than two frequency or rate selections. For those
waveforms, push the Frequency or Rate softkey to open
a scroll box above the softkey label with  next to it. Use

or  to select the frequency or rate. For those
waveforms that have only two frequencies or rates, the
Frequency or Rate softkey is a toggle, where each push
of the softkey switches to the other value.
