BACKGROUND Recent reports critical of the performance of heart rate-adjusted indexes of ST depression during exercise electrocardiography have used J-point rather than ST segment measurements. However, no standard exists for the optimal time after the J-point at which to measure ST segment deviation.
Here are some simple steps on how to measure the QRS complex: Find the QRS on the EKG strip. Determine where the QRS complex is, and to do this you start measuring the END of the PR interval to the END of S-wave. Count the SMALL boxes between there measurements. Remember each box represents 0.04 seconds. So, if you measure 2 boxes the measurement of the QRS complex would be 0.08.
