急性心肌梗死窦性心律震荡现象临床分析

目的 探讨窦性心律震荡现象对急性心肌梗死的影响.方法 分析急性心肌梗死(98例)与对照组(30例),急性心肌梗死存活组(75例)与死亡组(23例)的24 h动态心电图,比较各组间的心律震荡(HRT)的震荡初始(TO)和震荡斜率(TS).结果 ①与对照组TO、TS比较,急性心肌梗死组TO值高、TS值低,差异均有统计学意义(P＜0.05);②与急性心肌梗死存活组TO、TS比较,死亡组TO值高、TS值低,差异均有统计学意义(P＜0.05).结论 窦性心律震荡现象可作为急性心肌梗死死亡率的预测指标.Abstract：Objective To investigate the clinical value of heart rate turbulence(HRT) in acute myocardial infarction ( AMI). Methods HRT onset (TO) and HRT slope (TS) were calculat ed based on holter recorded in 75 survivors of AMI,23 cases died of AMI and 30 normal subjects.Results ①TO was higher and TS was lower in AMI patients than in normal subjects. ②TO was higher and TS was lower in cases died of AMI than in survivors of AMI. Conclusions HRT is relative to death and prognosis of with AMI.
