急性心肌梗塞早期血钾含量的临床研究

Clinical study of serum potassium in patients with early acute myocardial infarction

目的：探讨急性心肌梗塞（AMI）患者早期血钾含量与室性心律失常和梗塞部位的关系．方法：测定60例AMI发病6h内的血钾含量、室性心律失常发生率及梗塞部位，并分析其相关性．结果：不同梗塞部位组间血钾含量，经统计学处理有显著差异（P＜0．05），血钾低于3．5mmol／L的以右室、前壁梗塞为主，低血钾组室性心律失常的发生率为92．11％．结论：右室、前壁易发生低钾血症，低血钾症易发生心律失常，故AMI早期应及时补钾，提高AMI抢救成功率．

Objective: To study the correlation between serum potassium and vdricular myocardial inboion (AMI). Methods:The serum potassium and vertricular wtythmia and infarction.site were measured in the 60 patients 6 hours after AMI and the relations were analysed. Results:The serum potusium in the patients with AMI at different sites was significantly different (P<0.05).The serum potassium below 3.5mmol/Lwas detected more at the right ventricular and the antedor of the left ventricular after AMI than at other sites. The morbidity of the ventricular arrhythemia in hypopotassemia patients was 92.11%. Concluslon:Hypopotassemia wasoften detected at the left ventricular anterior and right ventricular aiter AMI, easily leading to arrhythmia Therefore, potassic drugs Should be used at the early Stage of AMI.
