[摘 要] 目的：探讨右室梗死心电图诊断标准的敏感性。方法：对17例确诊为右室梗死的心电图进行回顾性分析。结果：STV4r抬高≥0.1 mV是35.3%；STV4R抬高≥0.05 mV是71.1%；V3R～V6R导联ST段抬高≥0.1 mV是35.3%：V1～V5导联抬高的ST呈递减性是47%；STⅢ抬高>STⅡ抬高是47%；STV2下移/STavf抬高≤50%是11.1%；I、avL、V5、V6导联的Q波消失为53%；合并房室传导阻滞58.8%。结论:诊断右室梗死心电图的各项指标敏感性偏低。[关键词] 心电图；右室梗死；诊断标准

Abstract:Objective Discuss the sensitivity of diagnostic standareds of electrocardiography about right ventricular infarction.Methods Analyse the electrocardiography of 17 cases on right ventricular infarction that had been collected.Results The ratio of the ST elevation in V4R which is no less than 0.1 mV is 35.3%；The ratio of the ST elevation in V4R which is no less than 0.05 mV is 71.1%；The ratio of the ST elevation in V3R to V6R leads which is no less than 0.1 mV is 35.3%；The ratio of the ST elevation reduced by degrees in Vl to V5 leads is 47%；The ratio of the ST elevation in Ⅲ is more than the ST elevation in Ⅱis 47%；The ratio that between ST depression in V2 and ST elevation in avf is no more than 50% is 11.1%;The Q waves in Ⅰ、avL、V5、V6 had disappeared is 53%;The ratio of AVB is 58.8%.Conclusion The sensitivity of all indicators of diagnostic diagnostic standareds of electrocardiography about right ventricular infarction is a little lower. ......
