Both the roentgenographic assessment of heart size (CTR) and the evaluation of serial ECG are simple methods in diagnosing possible heart involvement in patients with pulmonary sarcoidosis. Heart rhythm disturbances (ventricular ectopic beats, atrial and ventricular tachycardia, bundle branch block, high degree av-block) are of particular diagnostic value especially in view of intermittent occurrence or therapeutic disappearance. Other noninvasive methods as vectorcardiography, echocardiography and nuclear myocardial imaging are of worth in confirming the diagnosis. There are some difficulties in differential diagnosis of other cardiomyopathies and ischaemic heart disease.
心脏大小的X线评估（心胸比率）和系列心电图评估都是诊断结节病患者心脏可能受累的简单方法。心律失常（室性早搏、房性和室性心动过速、束支传导阻滞、高度房室传导阻滞）具有特别的诊断价值，尤其是考虑到其间歇性发作或经治疗后消失的情况。其他非侵入性方法，如心电向量图、超声心动图和核素心肌显像，对确诊有一定价值。在与其他心肌病和缺血性心脏病进行鉴别诊断时存在一些困难。
