Biventricular Pacing: (also known as resynchronization therapy)


A biventricular pacemaker is designed to treat the delay in heart ventricle contractions. It keeps the right and left ventricle pumping together by sending small electrical impulses through the leads.


In a normal heart, both the upper (atria) and lower chamber (ventricle) pump at the same time. When a person has heart failure however, both chambers do not pump together. When the heart's contractions become out of sync, the left ventricle is not able to pump enough blood to the body. This eventually leads to an increase in heart failure symptoms, such as shortness of breath, dry cough, swelling in the ankles or legs, weight gain, increased urination, fatigue, or rapid or irregular heartbeat.

A Biventricular Pacemaker is usually recommended for heart failure patients who:

Have severe or moderately sever heart failure symptoms

Have been taking medications to treat heart failure

Have delayed electrical activation of the heart
