Cardiac magnetic resonance (CMR) is the gold standard for evaluating myocardial fibrosis. This study investigated the association between the occurrence and morphological features of ventricular arrhythmias (VAs) and left ventricular late gadolinium enhancement (LV-LGE) in patients without structural heart diseases. Seventy-eight patients with apparently normal hearts were enrolled and underwent simultaneous electrocardiogram and CMR examinations. Polymorphic VAs and ST-segment depression indicated a higher probability of having LV-LGE on CMR. The findings can help clinicians screen patients for CMR.
