What is the treatment for a right bundle branch block? Is this serious?

Nothing. There is no treatment for this. It is caused by a delay in the electrical system of your heart. Usually it just happens, but it can be caused by a previous heart attack, so you should ask your doctor about that. If it just happened, no heart attack, don't worry too much.
