Is bundle branch block serious?
Q. I had an electrocardiogram in preparation for minor surgery. My doctor told me it showed that I have right bundle branch block. Neither he nor my cardiologist are worried about it, but I am. Is this serious?
A. Much of the time, bundle branch block is not serious. If your doctors are telling you it's okay, I would trust them.
