Where do the limb leads go for a EKG?

In an electrocardiogram (EKG), the limb leads are placed on the patient's limbs as follows: Lead I is placed on the right arm (RA) and left arm (LA), Lead II on the right arm (RA) and left leg (LL), and Lead III on the left arm (LA) and left leg (LL). The right leg (RL) is typically used as a grounding electrode and is not involved in the lead formation. These placements help create a 12-lead EKG by providing various electrical views of the heart.
