Hi, was feeling sick short of breath and extremely dizzy with a funny feeling head ache. So I went to the ER and they gave me aN ECG and results were Borderline Q waves qs add 80 ms in 11 111 avf. They also did blood work and all was well, I'm assuming they checked the troponin for heart attack, check twice 6 hours apart. Was negative.. Any ideas what's going on?
