Does sarcoidosis cause right bundle branch block?
Nothing to be worried about at the moment
Greetings and welcome to HCM, thank you for your question. I understand your concern.
Yes, it is true that sarcoid disease would cause conduction abnormalities, but I do not think that this is the case. Your conduction abnormalities point more towards a congenital happening, which can be found up to 16% of the totally normal population of the world. If this is the case, it only should be monitored periodically through EKGs, to capture the moment when the conduction system is "getting old" and/or when symptoms, such as fainting or dizziness have started. And I am referring to the age of at least above 60 years old.
Sarcoidosis is a systemic condition which is accompanied with granulomatous formulations deposited within parenchyma (tissue) of some organs, it also may be deposited within the heart muscle. The more often than conduction abnormalities are cardiac arrhythmias. This condition has only some vague, non-specific changes in the EKG. The more specific exam that shows sarcoidosis of the heart (it is only when it os detected when cardiac arrhythmias and conduction abnormalities may be expected) is the echo cardiogram, which, in your case, did not show these granulomatous formations. Therefore, you have nothing to be worried about, at the moment, as your incomplete right bundle branch block combined with left anterior fascicular block, is not coming from your sarcoid disease. This is my opinion. However, I would recommend you to perform echo cardiogram on yearly bases. Even if it affects the heart, there are assist devices that do not treat sarcoid disease, but prevent sudden cardiac death.
I hope I was helpful with my answer. I am happy to help, if you have follow-up questions.
Hi again and welcome back.
Well, I would not recommend this exam right now, since there ar no symptoms nor there are evidence in the echo cardiogram. After all, it is an exam that shoul be done based on a clear-cut indication, not on the patient's free will - I think that is why the insurance would not cover for it.
I hope my follow-up is helpful.
