WebFigure 1. Electrode positions on an ECG (EKG). When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size. WebFind 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.
