Study Notes

Precordial Leads Overview

Precordial leads consist of six EKG leads positioned on the anterior chest.
These leads primarily capture electrical activity from the heart's ventricles and the anterior wall.

Chest Leads Designation

Precordial leads are also referred to as chest leads, identified as V1 through V6.

Lead Positions

V1: Located in the fourth intercostal space at the right sternal border.
V2: Positioned in the fourth intercostal space at the left sternal border.
V3: Placed equidistant between leads V2 and V4.
V4: Found in the fifth intercostal space along the left midclavicular line.
V5: Located in the fifth intercostal space at the anterior axillary line.
V6: Positioned in the fifth intercostal space at the left mid-axillary line.

General EKG Lead Identification

RA Lead (White): The electrode placed on the patient's right arm.
LA Lead (Black): The electrode placed on the patient's left arm.
RL Lead (Green): The electrode positioned on the patient's right leg.
LL Lead (Red): The electrode placed on the patient's left leg.
