How does a three lead pace maker work?

A three-lead pacemaker, often referred to as a biventricular pacemaker, is designed to synchronize the heart's chambers for more efficient pumping. It consists of one lead in the right atrium and two leads in the right and left ventricles. This setup allows for coordinated contraction of the ventricles, which is particularly beneficial for patients with heart failure or certain conduction disorders. By improving the timing of heartbeats, it enhances blood flow and can alleviate symptoms associated with heart rhythm problems.
