Normal QRS complex should be:
Tall
and narrow with no notches.
With tall R-wave completely above or below the baseline.
With pacer spike no higher than R-wave height.
With T-wave less than one-third of the R-wave height.
With P-wave much smaller than the T-wave.
For getting 1 mv calibrated ECG wave, choose ECG CAL button in ECG SETUP menu.
A
message
"when CAL, can't monitor! " prompts on the screen.
