急性心肌梗塞PTFv1变化及其意义的探讨

The Toxicity and Mutagenicity Test of Hyosphonoformate

本文对200例首发急性心肌梗塞（AMI）患者v1导联P波终末电势（PTFv1）变化进行分析，结果表明：PTFv1负值在不同年龄组分布差异非常明显（P＜0．01）．以年龄组对照，PTFv1负值越小差异越大。以临床心功能分级对比，PTFv1负值越大差别越明显．AMI前后PTFv1异常检出率差异极为显著（P＜0．005），说明AMI明显损害左心功能．近期预后分析，PTFv1负值大小与死亡无明显相关．文中提出诊断冠心病宜取PTFv1＜－0．02mm．s、判断心功能受损程度宜用PTFv1＜－0．04mm．s。

Evaluation of PTFv1 changes has been performed in 200 coses of newly-diagnosed acute myocardial infarction(AMI).The results showed:Distribution of PTFv1 salues varied significantly among age groups(P<0.01).In confrast with age group,ifthe PTFv1 negative value read smaller, the differences got greater.While the PTFv1 negative value read larger,the differences got much significantly as contrast with clinical cardiac function grades.There were very significant differences between the detection rates of PTFv1 abnormalities in patients before and after AMI(<0.005), These results represented cardiac function damage by AMI.Shortterm prognosis analysis revealed that there were no relation between PTFv1negative values and death rate.The author suggested:in diagnosis of coronary heart disesae,PTFv1 value criterion should be≤-0.02mm.s;while in judgement of cardiac function damage,it should be ≤-0.04mm.s.
