摘要:
目的 探讨预激综合征并发传导阻滞心电图PJ间期的变化。方法 选经导管射频消融术(RFCA)治愈的显性预激综合征并发传导阻滞者10例，分为3组，即旁路(AP)位于束支阻滞(BBB)同侧组，旁路位于BBB异侧组及并发Ⅰ°房室阻滞（AVB）组。分别测量各组术前、术后的PJ间期并比较PJ间期变化。结果 ① 6例旁路与BBB位于同侧的患者，术前PJ间期明显短于术后［（230±27）ms比（285±27）ms，P<0.01］，但其中1例术前PJ间期为270 ms（>260 ms）；② 2例AP与BBB位于异侧的患者，术前PJ间期短于术后（P<0.01）；③ 2例并发Ⅰ°AVB的患者，术前PJ间期明显短于术后PJ间期（P<0.01）。结论 ①预激综合征并发BBB时，PJ间期的变化取决于AP与正路的时差，AP与BBB的位置及AP距离心室最晚激动部位的远近，不能仅从AP的位置与BBB部位的关系来反映PJ的长短；②PJ间期的延长有可能为并发室内阻滞或AVB，宜进一步作食管心房调搏检查以明确诊断。
Abstract:
AIM To observe the effect of accessory pathway (AP) conduction on the PJ interval in patients with WolffParkinsonWhite syndrome associated with bundle branch block (BBB) or atrioventricular block(AVB). METHODS Included in the study were 10 patients with a single manifest AP associated with BBB or AVB who had undergone successful radiofrequency ablation (RFCA). The PR intervals, QRS durations and the PJ intervals were measured using simultaneous 12lead ECG before and after ablation. The effect of AP conduction on the PJ interval was investigated in WolffParkinsonWhite syndrome patients with BBB or AVB. RESULTS ① In the 6 patients whose bundle branch block and the pathway were at the same site, the duration of PJ intervals before RFCA was shorter than that after RFCA［（285±27）ms vs （230±27）ms，P<0.01］. ② In the 2 patients whose bundle branch block and the pathway were not at the same site, the duration of PJ intervals before RFCA was shorter than that after RFCA. ③ The duration of PJ intervals before RFCA was shorter than that after RFCA in patients with WolffParkinsonWhite syndrome associated with AVB. CONCLUSION ① The conduction via accessory pathway may mask the manifestations of BBB and AVB and simultaneously shorten the prolonged PJ intervals to some extent. ② The prolonged PJ intervals indicate that prolonged PJ intervals can be combined with AVB or BBB in patients with the preexcitation syndrome. However, PJ intervals in the normal range do not mean they are not associated with BBB.
