Treatments and drugsBy Mayo Clinic staff
There's no specific treatment for many cases of bundle branch block. 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.
And, if you have signs or symptoms, such as fainting, your doctor may recommend an artificial pacemaker to keep your heartbeat regular.
For some people with bundle branch block and a history of fainting, doctors may recommend implanting an artificial pacemaker. This pacemaker is a compact device that is implanted under the skin of your upper chest (internal pacemaker).
Internal pacemakers are placed near your collarbone during surgery performed using local anesthesia. The pacemaker generator connects to wires that go into your heart. The pacemaker provides electrical impulses when needed to keep your heart beating regularly. These devices have sensors that can detect when your heart is going too slow and needs a signal from the pacemaker to make your heart beat.
If you need a pacemaker, your doctor can explain any precautions you need to take in order to keep the device working properly and to reduce risks associated with its use.
