近年来国内外一些学者陆续报道了静脉应用硫酸镁治疗急性心肌梗塞(AMI),可预防心律失常、降低病死率。而QT离散度和急性心肌梗塞的心律失常发生率、猝死率有较高的相关性。现初步探讨了硫酸镁治疗急性心肌梗塞时对QT离散度的影响。
In recent years, some scholars at home and abroad have reported the intravenous application of magnesium sulfate in the treatment of acute myocardial infarction (AMI), can prevent arrhythmia and reduce mortality. QT dispersion and acute myocardial infarction incidence of arrhythmia, sudden death rate has a higher correlation. The effect of magnesium sulfate on QT dispersion in acute myocardial infarction is preliminary discussed.
