Since 10days post viral fever I am having pain inconsistent pain in chest(especially left), shoulder blade pain and also sometimes jaw pain, However 3months ago TMT,Echo both are normal again 2d echo done 10days before(before a day of viral fever) its also normal, However After viral fever, I have done ecg three 3 to 4 times, first one is - Normal Ecg with early-repolarization and (02nd) one is Normal ecg with T abnormality(Flat T) and third one is Normal with PR elevation in aVR and depression PR in rest lead. I am not sure why ecgs are some or other interpretation showing after fever. Before fever all my ecgs were normal with no such detection.
