Each QRS complex is evaluated as follows:
1. 
Select the colored profile from the Patient Screening Tool that best matches the amplitude of the QRS (Figure 5). For 
biphasic signals, the larger peak should be used to determine the appropriate colored profile. The QRS peak must fall 
within the window bounded by the dotted line and the peak of the colored profile.
Note: ECG gains > 20 mm/mV are not permitted. If, when printed at the maximum 20 mm/mV gain, the QRS 
peak does not reach the minimum boundary (dotted line) of the smallest colored profile, that QRS complex is 
deemed unacceptable.
Figure 5: 
2. SELECT the colored profile.  The largest  
QRS peak must be within a Peak Zone.
Selecting the colored profile
2. 
Align the left edge of the selected colored profile with the onset of the QRS complex.  The horizontal line on the 
colored profile should be used as a guide for  isoelectric baseline alignment.
