What causes right bundle branch block?

hello dr... im 28 years old and i have a rbbb... found it out a few years ago... then when i was examined by a cardiologist he said there was nothing and i also had a normal ecg and 2decho... today i was playing basketball and felt weak... i went to the e.r. and the internal medicine consultant told me i had rbbb... i have no other symptoms, just anxiety and felt a bit weak... i just wanted to ask if this could be caused by high cholesterol(ldl) levels? or is it something to worry about?

Hi

Thank you for expressing your concern here.

If I were treating you, I would not be too much concerned about Right bundle branch block if you did not have any associated disease in the heart. Right bundle branch block is associated with several structural heart diseases. But it appears that they are very less likely to be present in your case, from the history and the ECG & Echo report.

Isolated right bundle branch block is known to occur in several healthy individuals and there are so many studies done to prove that when they exist alone without any other heart disease they do not affect the long term health of the person.

Weakness could be because of many reasons. Did you check your hemoglobin? Please consider checking it, as iron deficiency anemia is one of the common causes of such weakness.

High cholesterol will not cause weakness usually. What were the levels of Cholesterol. If it is too high, treatment may be warranted for it.

Hope I answered your question!
