WebLeft bundle branch block is a problem in the heart’s electrical system. The heart has 2 main nerves 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 ... WebApr 14, 2024 · Delay in left ventricular depolarization is a more appropriate term because.
