摘要
对25例有确切 Kent 束(包括隐匿性)存在证据的顺传型房室反复性心动过速(AVRT)及27例慢快型房室结折返性心动过速(AVNRT)两组患者,作了室上速发作时食道单极导联心电图上室房传导时间(VA 间期)的对比研究。结果表明 AVRT 组的 VA 间期为80~140ms,而 AVNRT 组为0~70ms,两组间全无重叠。作者认为,VA 间期>70或≤70ms 是鉴别 AVRT 或AVNRT 的重要依据。
The ventricle-atrial conduction time(VA interval)in esophageal unipolar leadECG was comparatively studied during paroxysmal supraventricular tachycardia in 25patients with orthodromic atrioventricular reciprocating tachycardia(AVRT)and 27patients with slow-fast type of atrioventricular nodal reentrant tachycardia(AVNRT).The result indicated that VA interval of the patients with AVRT was 80 to 140msbut it was 0 to 70ms in the patients with AVNRT.No overlap was observed be-tween both groups. VA interval of>70 or≤70ms was considered an importent indicatorin differentiating AVRT from AVNRT.
