Biventricular pacemaker

A biventricular pacemaker is an option if you have moderate to severe heart failure or ventricular dysynchrony.

Dysynchrony occurs when the lower chambers (ventricles) of the heart beat separately instead of together. This causes inefficient pumping of the blood to the body.

Biventricular pacing involves the placing of two pacer wires. One wire will stimulate the right ventricle and the second wire will stimulate to left ventricle at the same time.

As a result, blood will be pumped more efficiently to the body. This pacemaker is also known as cardiac resynchronization therapy.
