Differentiating between sarcoidosis and giant cell myocarditis (GCM) based on clinical presentation is difficult. We present the case of a 57-year-old woman who was initially diagnosed with GCM based on endomyocardial biopsy. The patient was refractory to standard management for GCM and went on to develop bidirectional ventricular tachycardia, a finding suggestive of sarcoidosis. Unfortunately, the patient eventually needed cardiac transplantation. The explanted heart demonstrated cardiac sarcoidosis. Bidirectional ventricular tachycardia has not been demonstrated in GCM, and its presence may help in distinguishing between GCM and cardiac sarcoidosis.
基于临床表现来区分结节病和巨细胞性心肌炎（GCM）是困难的。我们报告一例57岁女性患者，最初根据心内膜心肌活检被诊断为GCM。该患者对GCM的标准治疗无效，继而发展为双向性室性心动过速，这一发现提示结节病。不幸的是，患者最终需要进行心脏移植。切除的心脏显示为心脏结节病。双向性室性心动过速在GCM中尚未得到证实，其出现可能有助于区分GCM和心脏结节病。
