I had an ECG done 11/9/13 at 1030am and it showed "incomplete right bundle branch block" had another one 11/10/13 11pm and it showed "normal sinus rhythm w/ sinus arrythmia and nonspecific st and t wave abnormality" I am 26 female and have normal to lower normal blood pressure, pulse is between 72-95 bpm most days and never had any other heart/chest problems--- until I had a head/chest cold 6-7 weeks ago. I never saw a dr about being sick but started noticing shoetness of breath during the cold and feeling winded just talking or walking. 2 weeks ago off and on randomly throughout the day I keep having sharp chest pains mid to right of my chest mainly; but also other places and sometimes the back as well. Are the 2 ecgs meaning the same thing? I also have anxiety and panic attacks but haven't been under stress lately or had a reason for anxiety until right now.
