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.

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… omni search bar omni search box excelNettet45 minutter siden · The Ohio State product is in the 97th or 98th percentile for height, weight, arm length, and hand size among offensive tackles.
