摘　　要：目的研究aVR导联中ST段抬高对阵发性室上性心动过速(PSVT)的诊断价值。方法分析PSVT发作时在aVR导联中ST段抬高情况,同时结合心电生理检查结果对其进行对比分析。结果 259例PSVT者按折返部位不同分为两组:①A组:房室折返性心动过速者158例,占61.00%;②B组:房室结折返性心动过速者101例,占39.00%。A组中PSVT发作时aVR导联ST段抬高者59例,占37.34%;B组中PSVT发作时aVR导联ST段抬高者79例,占78.22%。B组显著高于A组。A组中有左侧旁道参与的PVST者有75例(A1组),其中PSVT发作时aVR导联ST段抬高者64例,占85.33%。结论 aVR导联ST段抬高对有旁道参与的PVST有诊断价值,特别是左侧旁道参与者有十分明显的鉴别诊断意义。Objective Research lead AVR in ST-segment elevation of paroxysmal ventricular tachycardia(PSVT). Methods Analysis of PSVT attack lead AVR in ST-segment elevation,with electrophysiology check results contrast analysis. Results The aim of the 259 PSVT,atrioventricular reentrant tachycardia 158(Group A),accounted for 61.00%;Room reentrant tachycardia 101 cases(Group B),at 31.00%.A group PSVT attack aVR lead ST-segment elevation 59 cases,accounted for 37.34%;B group PSVT attack aVR lead ST-segment elevation to 79 cases,accounting for 78.22%.A group left side road participating PVST has 75 cases(Group A1),where PSVT attack aVR ST-segment elevation 64 cases,accounting for 85.33%. Conclusion aVR lead ST-segment elevation on the accessory pathways involved in diagnosis of PVST there,especially near the road participant has left very obvious diagnostic value.
