Dear patient

thanks for your concerns. the ekg as reported is for practical reasons quite normal; let me explain step by step; sinus rhythm is the normal rhythm of the heart. rsR prime pattern only means that there might be a discrete conduction delay of the electrical system of the heart, when the degree is higher it is called a right bundle block which you dont have ( blocked electrical activity to one side of the heart). Left axis deviation refers to the vector or direction of the electrical activity of the heart; enlargement of the left side chambers of the heart could cause that but also can be a normal variant in slim individuals.

If yoy have had a history of high blood pressure, those discrete changes could be explained by that, or if you are a slim person

best regards
