Right Bundle Branch Block: Symptoms, Causes, and Treatments
Written by Medicover Team and Medically Reviewed by Dr Daya S Vaswani , Cardiologist
Right Bundle Branch Block (RBBB) is a condition where the electrical conduction in the right side of your heart is delayed or blocked. This can impact how effectively your heart beats and may cause symptoms such as fatigue, dizziness, or breathlessness. Understanding its symptoms, causes, and available treatments is crucial to manage and prevent complications.
What are the Right Bundle Branch Block Symptoms and Warning Signs?
RBBB often goes unnoticed due to its subtle nature. However, recognising its signs early can be crucial to avoid further cardiac issues.
Common Symptoms
- Shortness of breath
- Light headedness
- Mild fatigue during exertion
- Irregular heartbeat
Severe Symptoms
- Chest discomfort or tightness
- Fainting spells
- Palpitations
- Severe breathlessness
What are the Different Types of the Right Bundle Branch Block?
RBBB is classified based on the severity of the conduction delay:
- Complete RBBB: Electrical signals are fully blocked on the right side, affecting heart rhythm significantly.
- Incomplete RBBB: Signals are only partially delayed, usually with fewer symptoms and lesser clinical impact.
Your cardiologist may identify the type using an ECG and recommend follow-up based on the severity.
What are the Common Causes and Risk Factors of Right Bundle Branch Block?
Understanding the causes and factors that increase your risk of developing RBBB can help you make informed lifestyle and healthcare choices.
Causes
- Coronary artery disease
- Heart attack (myocardial infarction)
- Congenital heart defects
- Cardiomyopathy
- Pulmonary embolism
Risk Factors
- Advancing age
- High blood pressure
- Chronic lung conditions like COPD
- Diabetes
- Smoking and sedentary lifestyle

Get Second OpinionHow is the Right Bundle Branch Block Diagnosed?
Diagnosing RBBB involves evaluating your heart's electrical activity and overall function. At Medicover, we use advanced tools to ensure accurate results.
Common Diagnostic Tests
- Electrocardiogram (ECG): The primary test that detects the conduction delay.
- Echocardiogram: Assesses the structure and pumping efficiency of your heart.
- Holter Monitoring: Records your heart's rhythm over 24-48 hours.
- Cardiac MRI or CT: For detailed structural imaging if needed.
What are the Treatment Options for the Right Bundle Branch Block?
The treatment depends on whether RBBB is isolated or caused by another condition. At Medicover, we tailor our care plans to each patient's heart health needs.
Medical Management
- Medications to treat underlying causes like hypertension or heart failure
- Oxygen therapy if related to pulmonary issues
Surgical & Device-Based Treatments
- Pacemaker implantation in severe or symptomatic cases
Recovery Timeline
- Mild cases may only need monitoring.
- Severe or symptomatic cases requiring a pacemaker usually recover within 2-6 weeks with proper follow-up.
Medicover's Approach: Our cardiologists follow an integrated approach combining medication, lifestyle management, and timely intervention to manage RBBB efficiently.
When to See a Doctor?
If you notice any of the following, prompt medical evaluation is recommended:
- Dizziness or fainting episodes
- Persistent fatigue
- Irregular heartbeat sensations
- A history of heart conditions or family history of cardiac conduction disorders
High-Risk Groups
- People aged 60 and above

What is the Recovery Process After Right Bundle Branch Block Treatment?
Recovering from RBBB treatment varies by case, but lifestyle support and routine follow-ups are key.
Follow-Up Schedule
- Initial review within 1 month of treatment
- Ongoing checks every 6-12 months depending on severity
Lifestyle & Diet Tips
- Reduce sodium intake
- Exercise moderately (as advised)
- Quit smoking and limit alcohol
- Monitor blood pressure regularly
Long-Term Outlook: Many individuals with RBBB live normal lives, especially when it is not linked to severe heart disease. Regular heart monitoring ensures better outcomes.
What Precautions Can Help Prevent Right Bundle Branch Block?
While not all causes are preventable, certain steps can reduce your risk and delay progression.
Prevention
- Maintain healthy blood pressure
- Manage chronic illnesses like diabetes or COPD
- Eat a balanced diet rich in heart-friendly nutrients
- Get regular cardiovascular check-ups
Complications if Untreated
- Worsening of heart rhythm disorders
- Increased risk of heart failure
- Higher chances of requiring a pacemaker
