The body acts as a large conductor of electrical currents generated by heart. To record, these currents require that only any two points on the body be connected to the electrocardiograph. This establishes the necessary completion of an electrical circuit and is done by means of electrodes attached to the limbs or the chest, each pair of attachments being one “lead.” The ECG leads generally used are I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, and V6.
