摘　　要：24h动态三导联同步记录并分析测定 30例急性心肌梗塞 (AMI)后 7± 4d的Holter心室晚电位 (HVLP)、心率变异性 (HHRV)、R -R间期均值的标准差 (SDNN)、QTc离散度 (HQTcd)和室性心律失常 (VA)、结果表明 :HVLP阳性与阴性组的HQTcd差异有显著性 (P <0 0 5 )、SDNN值差异无显著性 (P >0 0 5 )、恶性室性心律失常 (MVA)检出率差异有显著性 (P <0 0 1)。HVLP与SDNN间无相关性、与HQTcd密切相关 (r=0 6 8) ,HQTcd与SDNN间无相关性。提示 :HVLP能提高对AMI后VLP阳性检出率 ,同时监测上述指标可提高对AMI后高危患者的预测价值。To study the relation between Holter ventricular late potential(HVLP),correct QT dispersion(HQTcd),heart rate variability(HHRV) and ventricular arrhythm(VA), HVLP, HHRV, HQTcd and VA in 30 patients with acute myocardial infarction(AMI) were recorded after(7±4)days of onset. There was a dominant difference in the HQTcd(P<0 05),but SDNN value of HHRV (P>0.05) between the positive and negative group of HVLP. Detecting above indications at the same time was able to raise the value of prediction for the patients at high risk after AMI.
