Tetany is a state of hyperexcitability of the central and peripheral nervous system due to abnormal concentrations of serum electrolytes. However tetanic individuals without any detectable abnormalities, are also encountered. This last condition has been named "chronic normocalcemic tetany or spasmophilia". The case here reported, allows the authors to review the literature concerning normocalcemic tetany and let them focus on two similar and sometimes overlapping entities, spasmophilia and hyperventilation syndrome, both common causes of recurrent, atypical symptoms and tetany.
手足搐搦是由于血清电解质浓度异常导致的中枢和周围神经系统兴奋性增高的一种状态。然而，也会遇到没有任何可检测到异常的手足搐搦患者。后一种情况被称为“慢性血钙正常性手足搐搦或易痉挛症”。本文报告的病例使作者能够回顾有关血钙正常性手足搐搦的文献，并将重点放在两个相似且有时重叠的实体上，即易痉挛症和换气过度综合征，它们都是反复出现的非典型症状和手足搐搦的常见原因。
