Right bundle branch block (RBBB) is a condition where the electrical signals in the heart are delayed or blocked in the right bundle branch, which is part of the heart's conduction system. This can lead to a slower or altered heartbeat, affecting how efficiently the heart pumps blood. RBBB is often detected through an electrocardiogram (ECG), which shows characteristic changes in the heart's electrical activity. While it can occur in healthy individuals, it may also be associated with underlying heart conditions, such as coronary artery disease or pulmonary hypertension. Regular monitoring and evaluation by a healthcare provider are important for managing this condition.
