Cardiac magnetic resonance (CMR) imaging has gained significant traction as an imaging modality of choice in the evaluation of individuals with, or at risk for, heart failure. Ventricular arrhythmias, often malignant, may be sequelae of heart failure and arise from fibrosis. Late gadolinium enhancement evaluation by CMR has become a preferred modality to assess individuals at risk for malignant ventricular arrhythmias. A spectrum of various pathologies that predispose individuals to malignant ventricular arrhythmias, as well as the usefulness of CMR in their identification and prognostication, are reviewed.
心脏磁共振成像（CMR）作为评估心力衰竭患者或有心力衰竭风险个体的首选成像方式，已获得广泛应用。室性心律失常通常具有恶性，可能是心力衰竭的后遗症，由纤维化引起。CMR的延迟钆增强评估已成为评估有恶性室性心律失常风险个体的首选方式。本文综述了易导致个体发生恶性室性心律失常的一系列不同病理情况，以及CMR在识别和预测这些情况方面的作用。
