12 lead ECG (EKG) placement of electrode stickers: This tutorial will demonstrate the lead placement for the 12 lead ECG of the limb leads (RA: right arm, LA: left arm, RL: right leg, LL: left leg) and chest leads (V1, V2, V3, V4, V5, V6).
A 12 Lead ECG allows the nurse to assess the electrical activity of the heart. After obtaining a 12 Lead EKG the nurse can assess the patient’s heart rhythm and rate.
EKG electrodes are placed on the skin, and it is essential the nurse correctly preps the skin before placing the electrodes. For a 12 Lead EKG, you will need: 10 electrodes, alcohol prep (to clean the skin), abrasive tape, and hair trimmers. It is essential that excessive hair is clipped to prevent artifact in the EKG reading.

A 12-Lead ECG is an electrocardiogram that provides a comprehensive view of the electrical activity of the heart. It involves the placement of 10 electrodes on the chest, arms, and legs of the patient. The electrodes are connected to a machine that records the electrical signals generated by the heart.
The placement of the electrodes follows a specific protocol to ensure accurate readings. The first six electrodes are placed on the chest, with the V1 electrode placed in the fourth intercostal space to the right of the sternum, and the V2 electrode placed in the fourth intercostal space to the left of the sternum. The V3 electrode is placed midway between V2 and V4, while V4 is placed in the fifth intercostal space at the mid-clavicular line. V5 is placed at the anterior axillary line at the same level as V4, while V6 is placed at the mid-axillary line at the same level as V4 and V5.
The remaining four electrodes are placed on the limbs. The right arm electrode (RA) is placed on the right upper arm, while the left arm electrode (LA) is placed on the left upper arm. The right leg electrode (RL) is placed on the right lower leg, just above the ankle, and the left leg electrode (LL) is placed on the left lower leg, also above the ankle.
The electrode placement is crucial for accurate interpretation of the ECG results. The electrodes should be placed firmly on the skin to ensure good contact and minimize interference from movement or muscle activity. The patient should also be in a relaxed state, lying flat on their back, with no clothing or jewelry that could interfere with the electrode placement.
In summary, the 12-Lead ECG placement of electrodes involves the placement of 10 electrodes on the chest, arms, and legs of the patient following a specific protocol. The accuracy of the placement and the quality of the contact are crucial for accurate interpretation of the ECG results.
