Heart-related Condition: Symptoms, Remedies, and Prognosis (Regarding Right Bundle Branch Block)
Right bundle branch block (RBBB) is a common conduction abnormality affecting the electrical signals in the right ventricle of the heart. This condition, characterized by delayed conduction in the right bundle branch, leads to a prolonged QRS duration on an electrocardiogram (ECG) [1].
Causes of RBBB
RBBB in adults is often associated with various cardiovascular diseases and structural abnormalities affecting the heart's electrical conduction system [1][5]. Common causes include:
- Underlying heart conditions such as coronary artery disease, myocardial infarction (heart attack), cardiomyopathy, and valvular heart disease.
- Diseases affecting the conduction system, including degenerative fibrosis of the conduction pathways.
- Structural abnormalities such as right ventricular hypertrophy or dilation due to pulmonary hypertension or other causes.
- Congenital heart defects contribute but are less common in adult-acquired RBBB.
Symptoms and Risks
RBBB typically does not cause symptoms, but a severe block may cause a person to faint [2]. It's essential to note that RBBB may indicate underlying health issues or be associated with certain complications [3].
Risk factors for RBBB include advanced age, underlying heart disease, high blood pressure, underlying lung conditions, and electrolyte imbalances [4]. While RBBB is often the result of other underlying conditions or structural changes in the heart and is not always preventable, maintaining heart health and decreasing the risk of other underlying conditions is beneficial [6]. This includes getting regular exercise, eating balanced meals, maintaining a moderate weight, managing underlying health conditions, getting adequate sleep, and managing stress as much as possible.
Diagnosis and Treatment
Doctors diagnose RBBB using an ECG test [7]. In some cases, treatment for RBBB may be necessary due to underlying health issues such as heart failure, pulmonary embolism, or fainting episodes. If a person with RBBB experiences fainting episodes or significant conduction disturbances, a pacemaker may be recommended [8].
Outlook and Precautions
The outlook for a person with RBBB is generally favorable, but if RBBB is accompanied by other cardiac anomalies or underlying heart disease, the outlook may depend on the severity and management of those conditions [9]. People with RBBB who experience a heart attack or heart failure have a greater chance of mortality [10].
It is advisable to contact a doctor, such as a cardiologist, if a person has a new diagnosis of RBBB or experiences any concerning symptoms [5]. The CDC recommends that people with heart disease and associated risk factors, including RBBB, get a COVID-19 vaccination [11].

- Right bundle branch block (RBBB) is often linked to various cardiovascular diseases and structural abnormalities that affect the heart's electrical conduction system.
- Arrhythmia, cardiovascular disease, and cardiovascular health are essential medical-conditions to consider when managing RBBB, as they may cause significant complications.
- Maintaining a healthy heart and wellness, such as regular exercise and balanced meals, can decrease the risk of other underlying conditions and promote better cardiovascular health.
- A pacemaker may be recommended for individuals with RBBB who experience fainting episodes or significant conduction disturbances, as it could help regulate the heart's electrical activity.
