What does LBBB stand for in electrocardiography?

In electrocardiography, LBBB stands for Left Bundle Branch Block. This condition occurs when there is a blockage in the electrical pathways that lead to the left side of the heart, specifically affecting the left bundle branch. The left bundle branch is responsible for conducting electrical impulses to the left ventricle, allowing it to contract and pump blood effectively.

When there is a block in these pathways, the electrical impulses are delayed or obstructed, leading to a specific pattern seen on an electrocardiogram (ECG). This can result in various clinical effects and can be associated with underlying heart conditions, such as heart disease, hypertension, or previous heart attacks. Understanding LBBB is crucial for healthcare professionals because it can influence diagnosis, treatment plans, and the overall management of a patient’s cardiovascular health.
