Final answer:
Leads V5 and V6 are placed over the left side of the heart.
Step-by-step explanation:
The leads V5 and V6 are placed over the left side of the heart.
The human heart is divided into four chambers: two atria and two ventricles. The left side of the heart is responsible for sending oxygenated blood to the rest of the body in the systemic circuit, while the right side sends blood to the lungs for oxygenation in the pulmonary circuit.
When performing an electrocardiogram (ECG), six electrodes are placed on the chest to record the electrical activity of the heart. Leads V5 and V6 are two of these electrodes, and they are positioned specifically over the left side of the heart.
