What Right Bundle Branch Block Means for Your Heart Health

Right bundle branch block (RBBB) is a condition where electrical signals to the heart’s right ventricle slow down. This can affect how well the heart pumps blood and may lead to irregular rhythms. Often, people with RBBB show no symptoms and only discover it during a routine test like an electrocardiogram (ECG). RBBB happens when the heart’s electrical pathways are disrupted. Causes include lung issues such as pulmonary embolism, heart attacks, or infections in the heart tissue. High blood pressure, congenital defects like septal holes, and cardiomyopathy can also raise the risk. Even natural ageing changes in the heart may trigger the condition.

Diagnosing RBBB usually involves an ECG, which picks up the delayed electrical signals. While many people experience no noticeable effects, some may faint or feel lightheaded in rare cases. The condition can also complicate the detection of other heart problems, such as enlargement or failure. Treatment typically targets the underlying cause rather than RBBB itself. For example, managing blood pressure or treating infections can help restore normal heart function.

Most people with RBBB live normally without major issues. The condition often requires no direct treatment unless symptoms appear or an underlying problem is found. Regular check-ups and addressing related health concerns remain key to managing it effectively.
