Aim of this paper is to describe and discuss, on the basis of the available literature, the case of a young woman, previously colectomized for diffuse lipomatosis of the colon, showing hypomagnesemia and symptomatic (precordial discomfort) changes of repolarization phase, detected by ECG, probably due to coronary spasm. This hypomagnesemia (1.4 mEq/1) was probably due to altered intestinal absorption of magnesium, linked to a short bowel syndrome. The ECG changes and the precordial symptom were completely reversed by a relative short treatment with magnesium per os, which increased the magnesium level to low borderline value (1.6 mEq/1). The observation of ECG changes with precordial discomfort, probably linked to hypomagnesemia, suggests the need for routinary magnesium determinations to detect deficiency of this electrolyte, with the scope of improving the diagnosis and the treatment of several symptoms, otherwise difficult to interpret.
本文的目的是根据现有文献描述和讨论一名年轻女性的病例。该女性此前因结肠弥漫性脂肪瘤病接受了结肠切除术，出现低镁血症，心电图检测显示复极期有症状性（心前区不适）改变，可能是由于冠状动脉痉挛所致。这种低镁血症（1.4毫当量/升）可能是由于与短肠综合征相关的肠道镁吸收改变引起的。通过口服镁进行相对短期的治疗，使镁水平升至低临界值（1.6毫当量/升），心电图改变和心前区症状完全逆转。观察到的心前区不适的心电图改变可能与低镁血症有关，这表明需要常规测定镁以检测这种电解质缺乏，从而改善对一些难以解释的症状的诊断和治疗。
