Myocarditis/ MI combo meal at 23 due to reaction to Anthrax vaccine. Totally normal EKG before, abnormal since. SI was worded "any change in standards" triggering renewal. Had been since a couple years of EKG being abnormal but stable, as long as my EKG was "new normal" I required no further testing but akso had done restrictions on drugs I could take, BP/Resting HR had to stay normal etc.
