What are the Symptoms of Incomplete Right Bundle Branch Block?
October 21, 2023 | by Sravani Pathakamuri | Posted in FAQ's
An incomplete right bundle branch block (RBBB) is a relatively mild and common heart conduction abnormality. It is often detected on an electrocardiogram (ECG or EKG), a test that records the electrical activity of the heart. Incomplete RBBB is generally considered a benign condition and may not cause noticeable symptoms on its own. However, it can be associated with underlying heart issues or risk factors, and it is often identified during cardiac evaluations. Some individuals with incomplete RBBB may experience:
- No Symptoms: Many people with incomplete RBBB do not experience any symptoms at all. The condition is often discovered incidentally during routine ECGs.
- Mild Symptoms: In some cases, individuals with incomplete RBBB may report mild symptoms, such as occasional palpitations (awareness of heartbeats), mild fatigue, or shortness of breath during physical exertion.
Incomplete RBBB is characterized by a delay in the electrical conduction through the right bundle branch of the heart, which can affect the timing of electrical impulses and the coordination of heartbeats. However, it is generally not considered a serious condition on its own.
Incomplete RBBB may be a normal variant in some individuals, while in others, it can be associated with underlying heart conditions, such as hypertrophic cardiomyopathy, pulmonary hypertension, or other structural heart abnormalities. It can also occur in older adults as part of the aging process.
If an incomplete RBBB is identified, medical professionals will typically assess the individual’s overall heart health and may perform further tests or evaluations to rule out any underlying heart conditions. In most cases, no specific treatment is required for incomplete RBBB itself. Management, if necessary, will focus on addressing any underlying heart issues or risk factors that may be present. It’s important for individuals with incomplete RBBB to follow up with their healthcare provider for proper evaluation and recommendations, especially if they experience concerning symptoms or have other heart-related conditions.
