Multiple endocrine neoplasia type 2B is a genetic disorder characterized by pheochromocytoma, medullary thyroid carcinoma, and marfanoid features. Although hypertension and stress cardiomyopathy are known cardiovascular complications of pheochromocytoma, clinical presentation maybe subtle. Elevation in heart rate and lightheadedness induced by catecholamine excess may mimic clinical features of postural orthostatic tachycardia syndrome, as shown in our case report. ().
2B型多发性内分泌腺瘤病是一种遗传性疾病，其特征为嗜铬细胞瘤、甲状腺髓样癌和类马凡氏体型外貌。虽然高血压和应激性心肌病是已知的嗜铬细胞瘤心血管并发症，但其临床表现可能不明显。如我们的病例报告所示，儿茶酚胺过量引起的心率升高和头晕可能会模仿体位性直立性心动过速综合征的临床特征。（）
