である。An electrocardiogram is usually a time-series record of potential differences derived from one or more leads, but one lead means a combination of at least two electrodes, and there are currently no known induction methods. The standard is 12 leads: standard limb leads (3), unipolar limb leads (3), and unipolar thoracic leads (6).
