Where is the placement of electrodes in a 3 lead bipolar ECG?

In a 3-lead bipolar ECG, electrodes are placed on the body to create three leads: Lead I, Lead II, and Lead III. Typically, the positive electrode for Lead I is placed on the left arm, and the negative electrode on the right arm. For Lead II, the positive electrode is on the left leg, while the negative remains on the right arm. Lead III has the positive electrode on the left leg and the negative on the left arm.
