Question:
Is RBBB associated with seizures?
I am a 41 year old female and was diagnosed by ECG [echocardiogram] with RBBB [right bundle branch block] when I went to the doctor to report chest pain. I am in overall good health and get a yearly physical. While reading up on RBBB, I came across information on LQTS [long Q-T syndrome]. I had a series of seizures that began while I was an infant, usually when my mother bathed me or changed my diaper and I would pass out. The doctor then told her that if the "seizures" didn't cease by the age of 6, to come back for testing. Last seizure was at age 4-5. Could the RBBB be associated with the seizures? Do RBBB and LQTS have anything to do with one another? My primary care physician says not to worry about the RBBB. But at the time of my appointment, I didn't think to mention the childhood seizures. Thank you.

Right bundle branch block (RBBB) is not associated with seizures. RBBB and Long Q-T Syndrome (LQTS) have no relationship. LQTS is usually apparent on the ECG. The fact that you have not had any seizures or fainting in 35 years is a very good sign.
