Despite significant stenosis in the coronary arteries, there was no evidence of acute or old myocardial infarction, heart failure, myocarditis or structural abnormalities on post-mortem to account for the substrate for the fatal arrhythmia. The refractory and incessant nature of the ventricular fibrillation and post-mortem finding of a grossly elevated unexplained IgE level (in the absence of acute myocardial infarction) suggested the possibility of Kounis Syndrome or allergic acute coronary syndrome. %K Refractory Ventricular Fibrillation %K COVID-19 Vaccine %K Kounis Syndrome %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=135512
