[|Human|] Im 42 years old and recently had my yearly preventive physical exam. My total cholesterol is 195, with a 116/80 BP. Active runner/biker, and have not experienced any fainting etc. I was told to have RBBB.  Should I be concerned? Can I keep running etc. without concern?
[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your little concern. But you have nothing to worry about. I compliment you for having the initiative to make yearly check up. The right bundle branch block means a particular conduction of the electrical impulse in the heart. In a lot of cases it is a normal variant of your electrocardiogram pastern. This is frequently seen in young ages and doesn't mean any cardiac pathology. So, if you have done other examinations, like an echocardiography and you don't have any complain we may say that we have nothing to worry about, this is quite normal. You can keep running without concern because it dost mean anything, you do not have any pathology, this is called a normal variant, like different eye colors. My opinion as cardiologist is to continue your normal live and keep training and doing your yearly check up. Hope I was helpful. Wish you good healthiest regards
