11.2.2.4 Characteristics of Quality ECG Signal
As shown in Figure 11-6, the normal QRS complex should exhibit the following
characteristics.
îš„ Tall and narrow with no notches.
îš„ With a tall R-wave completely above or below the baseline.
îš„ With a pacer spike no higher than the height of the R-wave.
îš„ With the T-wave less than one-third of the height of the R-wave.
îš„ With the P-wave much smaller than the T-wave.
Figure 11-6 Standard ECG Waveform
To display a 1-millivolt calibration pulse on the ECG wave, select the ECG CAL
option in the ECG SETUP menu. A message "when CAL, can't monitor! " is
displayed on the screen.
NOTE
z If the ECG waveform is too small, or not accurate, and the electrodes are
secure and firmly attached to the patient, change the display to a
different lead.
