NettetThe six precordial electrodes act as the positive poles for the six corresponding precordial leads: (V 1, V 2, V 3, V 4, V 5, and V 6). Wilson's central terminal is used as the negative pole. Recently, unipolar precordial leads have been used to create bipolar precordial leads that explore the right to left axis in the horizontal plane. NettetThe standard ECG – which is referred to as a 12-lead ECG since it includes 12 leads – is obtained using 10 electrodes. These 12 leads consists of two sets of ECG leads: limb leads and chest leads. The chest leads may also be referred to as precordial leads . …

Electrodes are the actual conductive pads attached to the body surface. Any pair of electrodes can measure the electrical potential difference between the two corresponding locations of attachment. Such a pair forms a lead. However, "leads" can also be formed between a physical electrode and a virtual electrode, known as Wilson's central terminal (WCT), whose potential is defined as the a…
