Cardiac arrhythmias are associated with significant morbidity, mortality and poor quality of life. Cardiovascular magnetic resonance (CMR) imaging, with its unsurpassed capability of non-invasive tissue characterisation, high accuracy, and reproducibility of measurements, plays an integral role in determining the underlying aetiology of cardiac arrhytmias. CMR can reliably diagnose previous myocardial infarction, non-ischemic cardiomyopathy, characterise congenital heart disease and valvular pathologies, and also detect the underlying substrate concealed on conventional investigations in a significant proportion of patients with arrhythmias. Determining the underlying substrate of arrhythmia is of paramount importance for treatment planning and prognosis. However, CMR imaging in patients with irregular heart rates can be problematic. Understanding the different ways to overcome the limitations of CMR in arrhythmia is essential for providing high-quality imaging, comprehensive information, and definitive answers in this diverse group of patients.
心律失常与显著的发病率、死亡率及生活质量低下相关。心血管磁共振（CMR）成像凭借其在无创组织特征描述方面无与伦比的能力、高精度以及测量的可重复性，在确定心律失常的潜在病因中发挥着不可或缺的作用。CMR能够可靠地诊断既往心肌梗死、非缺血性心肌病，明确先天性心脏病和瓣膜病变的特征，并且在相当一部分心律失常患者中，还能检测出常规检查所隐匿的潜在病变基础。确定心律失常的潜在病变基础对于治疗方案的制定和预后至关重要。然而，心率不规则患者的CMR成像可能存在问题。了解克服CMR在心律失常方面局限性的不同方法，对于为这类多样化患者群体提供高质量成像、全面信息及明确答案至关重要。
