3.Among them there were atrioventricular reentrant tachycardia(AVNRT) in 55 cases,artrial ventricular reentrant tachycardia(AVRT) in 106 cases,idiopathic ventricular tachycardia(IVT) in 4 cases,atrial flutter(AFL) in 5 cases.
房室结折返性心动过速 (AVNRT) 5 5例 ,房室折返性心动过速 (AVRT) 10 6例 ,特发性室性心动过速 (IVT) 4例 ,阵发性心房扑动 (AFL) 5例。
4.Results There were 114 cases of atrioventricular nodal reentrant tachycardia(AVNRT), 117 cases of atriventricular reentrant tachycardia (AVRT), 4 cases both have AVNRT and AVRT, 5 cases of atrial tachycardia (AT), 3 cases of atrial flutter (AF) and 1 case has AVNRT and AT.
结果房室结折返性心动过速114例,房室折返性心动过速117例,房室结折返合并房室折返性心动过速4例,房速5例,房扑3例,房室结折返性心动过速合并房速1例。
5.Results:AH intertval and AV interval in group Ⅰ (short PR interyal group)were shorter than these in group Ⅱ(normal PR interval),vdry significantly ( P <0 01),supraventricular tachycardia mechanism in Ⅰ group were atrioventricular nodal reentrant tachycardia in 20 cases and atrioventricular reentrant tachycardia in 6 cases.
结果Ⅰ组(短PR组)的AH间期和AV间期明显短于Ⅱ组(PR间期正常组)的AH间期和A-V间期,差异有显著性,P<0.01; Ⅰ组室上性心动过速的电生理机制是20例为房室结折返性心动过速,6例为房室折返性心动过速。
6.Patients with AF were classified by group A(25 patients),3 of which coexisted with atrioventricular nodal reentrant tachycardia(AVNRT),4 with atrioventricular reentrant tachycardia(AVRT) and 10 with paroxysmal atrial tachycardia(PAT).
其中A组同时合并房室结折返性心动过速(AVNRT)3例,房室折返性心动过速(AVRT)4例,阵发性房性心动过速(PAT)10例;
7.AV reentrant tachycardia due to concealed accessory pathway to the effective of the tachycardia features
房室折返性心动过速旁道传导性质对心动过速发作特征的影响
8.13 patients with recurrent sustained ventricular tachycardia and no demon- strable heart disease exhibiting a pattern of right bundle branch block with left axis diviation,QRS complex wave duration ≤0.12 second during tachycardia were reported.
本文报告13例无明显器质性心脏病、心电图示 QRS 时限≤0.12秒、呈右束支阻滞伴电轴左偏图形的反复发作持续性 VT 患者。
9.(3)For the diagnosis of ortho-dromic A-V reentrant tachycardia or slow-fast AV nodal reentrant tachycardia. there were very high sensitivity, specificity and diagnostic accuracy when cut-points of Pv,-PE>25ms, R-PE>100ms or Pv1-PE≤25ms, R-PE≤100ms were used, respectively.
(3)根据P_V_1-P_E(绝对值)>25ms、R-P_E>100ms诊断正向型房室折返性心动过速,根据P_V_1-P_E(绝对值)≤25ms、R-P_E≤100ms诊断慢-快型房室结折返性心动过速均有很高的敏感性、特异性和准确性。
