Bundle Branch Block

Bundle Branch Block (BBB) is a condition that affects the heart's electrical system, specifically how signals travel through the heart's ventricles. Typically, the heart beats in a coordinated fashion, allowing efficient pumping of blood. In BBB, one of the bundle branches (pathways) that relay electrical signals to the heart's lower chambers is blocked or delayed. This can lead to a slower or altered heartbeat. While some people may not experience any symptoms, others might have issues like dizziness or fatigue. It's often identified using an electrocardiogram (ECG), and treatment depends on the underlying cause and symptoms.
