A doctor has provided 1 answer

Rate related delay: You have a "rate related LBBB" meaning that as your heart speeds up, the conduction through the His-Purkinje network of fibers (conducting tissue in the heart muscle) take a longer time than normal to repolarize (prepare electrically for the next impulse). As I said in my previous post to you, trust your EP doctor.
