使用心电图确诊急性心肌梗死间合完全性左束支传导阻滞的结果分析【摘要】目的：探讨采用心电图（ECG）对急性心肌梗死（AMI）间合完全性左束支传导阻滞（CLBBB）进行临床诊断，并对结果进行分析。方法：选取189例CLBBB患者进行心肌酶检查，结果显示其中有19例AMI患者，对其心电图特征进行分析。结果：19例患者当中，2例广泛性前壁心肌梗死，V1-V3呈rS型导联，V6导联的QRS波群呈顶端粗钝且宽阔的R波，V1-V4的ST段弓背呈0.3-0.5mV的抬高，STV5、V6、I、aVL导联呈0.1-0.2mV的斜上方抬高；7例下壁心肌梗死，其中5例Ⅱ、Ⅲ、aVF导联均为QS型，ST段弓背呈0.3-0.5mV的抬高，T波呈直立；10例前间壁心肌梗死，其中9例的V1、V2、V3导联呈QS型，8例V1、V2、V3导联ST段的单向弓背呈0.4-0.8mV的抬高，T波呈直立，且无法轻易识别J点，4例ST段的抬高情况与T波呈“R”型。结论：在心电图的检测当中，QRS主波以及Q波向下时，ST段的单向弓背呈0.3-0.8mV的抬高，或QRS主波为向上时，ST段呈0.1-0.2mV的斜上方抬高，这对AMI间合CLBBB的临床诊断具有重要的价值与意义。【关键词】心电图监测；急性心肌梗死；完全性左束支传导阻滞；临床诊断UsingECGdiagnosisofAcuteMyocardialInfarctionAmongco-completeLeftBundleBranchBlockAnalysisoftheResultsWangXiufang(Sanya,HainanLandReclamationBureauHospitalfeaturesSanya,Hainan572000)【abstract】objective:tostudytheelectrocardiogram(ECG)onacutemyocardialinfarction(AMI)andcompleteleftbundlebranchblock(CLBBB)forclinicaldiagnosis,andanalyzetheresults.Methods:choose189casesofpatientswithCLBBBmyocardialenzymeexamination,theresultshowsthereare19patientswithAMI,toanalyzetheecgcharacteristics.Results:19casesofpatients,2casesofextensiveanteriorwallmyocardialinfarction,leadV1-V3isrS,V6leadQRScomplexisbluntandwideatthetopoftheRwave,V1-V4STsegmentofthearchof0.3to0.5mVdriveup,STV5,V6,theI,leadaVLis0.10.2mVinclinedtopup;7casesofinferiorwallmyocardialinfarction,with5Ⅱ,Ⅲ,typeofaVFleadareQS,STsegmentofcamberis0.3to0.5mVdriveup,Twaveisupright;Partitionbefore10casesofmyocardialinfarction,including9casesofV1,V2,V3leadQStype,8casesofV1,V2,V3leadSTsegmentofone-wayarchis0.4to0.8mVdriveup,Twaveisupright,andcannoteasilyidentifyJpoints,4casesofelevationofSTsegment...
