 [ Symptoms ] i have residue in the part in my hair i have tried switching shampoosconditioners and it did not help what should i do [ Disease ] i have right bundle branch block and my physician not was not concerned he explained to me that if it had been a left bundle branch block that he may have done investigation beyond my e k g test according to my doctor the majority of cardiac work is completed on the left side my understanding is that a left bundle branch block may have little to no significance or its presence could indicate underlying cardiac disease left bundle branch block is sometimes seen with cardiac enlargement aortic valve disease and a host of other cardiac conditions although most organs of the body work like a finely tuned orchestra irritable bowel syndrome and back problems more than likely are issues not related to a diagnosis of left bundle branch block i would not ignore the lbbb finding and recommend that you discuss it with your doctor and determine if further workup is needed perhaps a referral to a competent cardiologist heart specialist is justified
