摘　　要：目的探讨SV2/RV3指数与QRS波时限和QRS波方向定位诊断室性早搏或室性心动过速起源部位。方法应用SV2/RV3指数定位诊断室性早搏或室性心动过速起源部位的240例患者组(观察组)和应用传统的QRS波时限和QRS波方向定位诊断室性早搏或室性心动过速起源部位的240例患者组(对照组)对比分析。结果观察组中SV2/RV3比值≤1.5mV提示室性早搏或室性心动过速起源于左室流出道者124例(51.66%)和SV2/RV3比值>1.5mV提示起源于右室流出道者116例(48.33%),p>0.05。对照组中QRS波群时限≥0.12s,I、V5、V6导联QRS波群呈R型,V1、V2导联QRS波群呈r S型,Ⅱ、Ⅲ、aVF导联主波向上,室性早搏或室性心动过速起源于右室者122例(50.83%),QRS波在Ⅱ、Ⅲ、aVF导联主波向上,V1~V6导联主波向下或Ⅱ、Ⅲ、a VF导联主波向下,V1~V6导联主波向上,室性早搏或室性心动过速起源于左室118例(49.16%),p>0.05。两组中各35例接受射频消融术终止室早或室速:观察组25例(80.00%),对照组15例(42.85%),p<0.01。结论应用SV2/RV3比值诊断室性早搏或室性心动过速的起源部位优于传统的QRS波时限或QRS波方向诊断室性早搏或室性心动过速的起源部位,对射频消融术的筛选具有实用价值。Objective To origin region using of SV2/RV3 index and traditional QRS time limit and QRS direction location disagnostic ventricular arrhythmia. Methods Using of SV2/RV3 index location disagnostic ventricular premature or ventricular tachycardia origin region 240 in patients group(observed group)and using traditional QRS time limit and QRS direction location disagnostic ventricular premature or ventricular tachycardia origin region 240 in patients group(compared people)comparison analyzing. Results In observed group SV2/RV3 ratio ≤1.5 mV display ventricular premature or ventricular tachycardia origin region lef ventricular effluent tract 124 patients(51.66%), and SV2/RV3 ratio>1.5 mV display ventricular premature or ventricular tachycardia origin region right ventricular effluent tract 116 patients(48.33%), p>0.05. In patients compared people QRS complex time limit≥0.12 s, I、V5、V6 lead QRS complex presentation R from, V1、V2 lead QRS complex presentation r S from,Ⅱ、Ⅲ、a VF lead main wave upward up,ventricular premature or ventricular tachycardia origin region right ventricular 122 patients(50.83%), QRS wave Ⅱ、Ⅲ、aVF lead wave upward up, V1V6 lead wave upward down or Ⅱ、Ⅲ、aVF aVF lead wave upward wave down, V1V6 F lead wave upward up, ventricular premature or ventricular tachycardia origin region lef ventricular 118 patients(49.16%), p>0.05.Two group every 35 accept radiofrequency catheter ablation termination ventricular premature or ventricular tachycardia: the observed group termination ventricular premature or ventricular tachycardia in 25 patients(80.00%),the compared people termination ventricular premature or ventricular tachycardia in 15 patients(42.85%), p<0.01.Conclusions Using SV2/RV3 index ratio SV2/RV3 index location disagnostic ventricular premature or ventricular tachycardia origin region excellent using traditional QRS time limit and QRS direction location disagnostic ventricular premature or ventricular tachycardia origin region, to radiofrequency catheter ablation of
