急性心肌梗塞病人高频心电图分析及动态观察的临床意义

THE CLINICAL SIGNIFICANCE OF ANALYSIS AND DYNAMIC CHANGE IN HIGH FREQUENCY ELECTROCARDIOGRAM OF ACUTE MYOCARDIAL INFARCTION

本文对２８例急性心肌梗塞病人及２０例正常人做了高频心电图检查。并对１２人做了３－４周的动态观察。结果表明：急性心肌梗塞患者高频成分明显增多，有并发症者高频成分增加更明显，动态观察显示，急性心肌梗塞患者第２周高频成分减少，第３－４周高频成分又稍增加，反映了急性心肌梗塞的病情变化。

The high frequency electrocardiogram were analyzed in 28cases of acutemvocardial infarction(AMI)and 20 healthy subjects,dynamic observation were recorcled in12 of 28 cases of AMI for 3-4weeks.The results showed that:Numbers of high frequencycomponents in patients with AMI increased significantly than that in nownal subjects(P<0.001);Numbers of high frequency components in patients with complicated myocardial in-farction were more higher than that in no complicated myocardial infarction; Numbers of highfrequency components in pationts with AMI decreased during 2nd week amd iricreased duringthe 3rd to 4th week.
