Left bundle branch block is a problem in the heart’s electrical system. The heart has 2 main pathway that cause the heart to contract. They are called bundle branches, and they connect the top and bottom chambers of the heart. In left bundle branch block, the left bundle branch doesn't work correctly. This causes the left lower heart chamber (ventricle) of the heart to squeeze later than normal.
If you have no symptoms or other heart problems, you may not need treatment. If you have symptoms or other heart problems, you may need treatment, such as:
Pacemaker. A device is put into your chest to help your heart pump normally using wires placed in the heart.
Cardiac resynchronization therapy (CRT). A special pacemaker is put into your chest with wires controlling both left and right ventricles. It helps the lower chambers of the heart (ventricles) pump normally. CRT may be used if you have heart failure and left bundle branch block.
People with no symptoms and no other heart problems are unlikely to have complications. In other cases, complications may include:
Heart failure
Dizziness or fainting from low heart rate called heart block
Heart that stops beating (cardiac arrest)
