What lead is also called bipolar?

The lead commonly referred to as "bipolar" is the bipolar lead in electrocardiography (ECG). This lead configuration consists of two electrodes, one positive and one negative, placed on the body to measure the electrical activity of the heart. Unlike unipolar leads, which measure voltage from a single electrode to a reference point, bipolar leads capture the difference in electrical potential between two points, providing a more comprehensive view of the heart's electrical activity. The most common example of a bipolar lead is Lead II, which connects the right arm and left leg electrodes.
