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. Web5 nov. 2024 · Small squares are 1 mm across and represent 0.04 seconds. The large squares measure 5 mm across and represent 0.2 seconds. 10 mm in height is equal to 1mV in voltage. Interpreting these values will help you determine if the heartbeat is irregular, or too fast or too slow. [2] 2 Find the QRS complex and label it on the handout.
