Treatments and drugsBy Mayo Clinic Staff
Most people with bundle branch block are symptom-free and don't need treatment.
However, if you have an underlying heart condition causing bundle branch block, treatment of the underlying condition is recommended. Treatment of underlying conditions may involve using medications to reduce high blood pressure or lessen the effects of heart failure, or the use of a coronary angioplasty to open up the artery leading to your heart.
Additionally, depending on your symptoms and whether you have other heart problems, your doctor might also recommend:

- A pacemaker. For some people with bundle branch block and a history of fainting, doctors may recommend implanting a pacemaker. A pacemaker is a compact device implanted under the skin of your upper chest (internal pacemaker) with two wires that connect to the right side of your heart. The pacemaker provides electrical impulses when needed to keep your heart beating regularly.
- Cardiac resynchronization. Also known as biventricular pacing, this procedure is similar to having a pacemaker implanted. However, in cardiac resynchronization, there's a third wire that's connected to the left side of the heart so the device can keep both sides in proper rhythm.
