用食管调搏法回顾性地观察了38例病窦患者房室传导文氏点(WP)的发展情形。随诊12～141个月,平均62.5个月。初测WP≤130次/分组中WP下降的例数略多于初测WP>130次/分组(55.6%比17.2%,P<0.05)。10例(26.3%)文氏点下降,平均下降13次/分。全组患者无一例出现临床上的房室传导阻滞。SNRTm的延长与文氏点的下降没有相关性(P>0.05)。本资料结果表明,AAI型起搏器可以较多地应用于无明显房室传导阻滞的病窦患者。
The esophageal pacing method was used to retrospectively observe the development of atrioventricular Ventricle (WP) in 38 patients with sick sinus. Follow-up 12 to 141 months, an average of 62.5 months. The number of cases with WP falling less than 130 times per group in the initial test was slightly more than that of the initial test with WP> 130 beats / group (55.6% vs. 17.2%, P <0.05). Ten cases (26.3%) Wen’s point decreased, with an average decrease of 13 beats / min. None of the patients in the whole group had clinical atrioventricular block. There was no correlation between SNRTm extension and Wen’s point decline (P> 0.05). The data results show that AAI-type pacemaker can be more used in patients with sinus disease without obvious AV block.
