In a Left Vs. Left Bi-V Pacing (Biventricular Pacing) and His/Purkinje conduction system pacing approach, the focus is on synchronizing the left ventricle with the right ventricle to enhance cardiac function, particularly in patients with heart failure. During these procedures, three leads are typically utilized.

One lead is placed in the right atrium to capture atrial activity, another lead is positioned in the right ventricle to stimulate ventricular contraction, and the third lead is placed specifically in the left ventricle. This configuration allows for the effective pacing of both ventricles, improving coordination and overall myocardial performance.

The setup aims to take advantage of the conduction system, ensuring that electrical impulses flow through the heart in a coordinated manner, which is essential for maintaining effective cardiac output. Thus, the answer indicating that three leads are used aligns perfectly with the requirements of left-sided ventricular pacing strategies.
