摘要
目的了解食道心房调搏在房室传导功能检测中的意义。方法对39例PR间期延长(研究组)和141例PR间期正常(对照组)患儿房室传导功能进行了经食道心房调搏研究。结果在非房室结双径路和多径路者,研究组的房室传导有效不应期、文氏传导阻滞点及同一刺激频率的SV间期较对照组为长。但在房室结双径路和多径路者,研究组和对照组文氏传导阻滞点及同一刺激频率的SV间期以及快径路的有效不应期和功能不应期无显著性差别。
Objective To understand the value of the transesophageal pacing in test of atrio-ventricular conduction function.Methods The transesophageal pacing was performed in 39 children with prolonged PR interval(study group) and 141 children with normal PR interval(control group).Results The atrio-ventricular effective refractory period,Wenchebach atrio-ventricular block point and SV interval at the same stimulus rate were longer in study group than those in control group in case of non-dual and non-multiple pathway,but Wenchebach atrio-ventricular block point,SV interval at the same stimulus rate,as well as atrio-ventricular effective and functional refractory periods of fast pathway had no significant difference between the control group and study group in case of dual and multiple pathway.Conclusion The transesophageal pacing plays certain role in examining the atrio-ventricular conduction function.
