Biventricular Pacemaker / Cardiac Resynchronization Therapy (CRT)
Used in cardiac resynchronization therapy (CRT), the biventricular pacemaker is used to synchronize the pumping of the heart's ventricles (lower chambers) with the pumping of the heart's atria (upper chambers).

Another type of heart failure causes a delay in the contractions of the ventricles, making the left and the right ventricle to pump "out of sync". This leads to a rapid or irregular heartbeat, as well as the left ventricle not being able to pump enough blood to the body. The biventricular pacemaker synchronizes the pumping between the left and the right ventricle, returning the heartbeat and blood flow to normal.
