CRP and Arrhythmia: Previous work reported a correlation between EBV and myocarditis.7 Arrhythmias are well-known consequences of myocarditis, ranging from ventricular arrhythmias to atrial fibrillation, atrioventricular blocks, and complete heart blocks.8 However, our patient did not show signs of overt myocarditis, since both C-reactive protein and troponin were normal, and the CMR showed no significant findings.
