In 176 patients with acute myocardial infarction (AMI) serum magnesium concentration (MGK) and serum potassium concentration (KK) were analysed during the first 48 hours after AMI. The patients rhythm was continuously recorded. In a subgroup of 70 patients a signal averaging-ECG was performed. 4.5% of the patients had a low, 55.7% a normal and 39.8% a high MGK. 14.8% of the patients had a low, 80.1% a normal and 5.1% a high KK. Ventricular arrhythmias > or = Lown IV b were found in 25% of the patients with low MGK, in 38.8% with normal and in 52.9% with high MGK. 50% of the patients with low, 62.2% with normal and 61.3% with high MGK had late potentials. There was no relation between hypomagnesemia and ventricular arrhythmias as between hypomagnesemia and late potentials. Thus, hypomagnesemia in AMI patients is rare and does not correlate with ventricular arrhythmia or delayed ventricular potentials.
对176例急性心肌梗死（AMI）患者在AMI发作后的最初48小时内分析了血清镁浓度（MGK）和血清钾浓度（KK）。持续记录患者的心律。在70例患者的亚组中进行了信号平均心电图检查。4.5%的患者MGK低，55.7%正常，39.8%高。14.8%的患者KK低，80.1%正常，5.1%高。MGK低的患者中25%出现室性心律失常≥洛恩IV b级，MGK正常的患者中38.8%出现，MGK高的患者中52.9%出现。MGK低的患者中50%、MGK正常的患者中62.2%、MGK高的患者中61.3%有晚电位。低镁血症与室性心律失常之间以及低镁血症与晚电位之间均无关联。因此，AMI患者中低镁血症罕见，且与室性心律失常或心室延迟电位无关。
