为探讨窦性心动过缓病人房室结多径路传导的发生情况。观察多径路的发生率,并着重分析其与年龄、基础窦性心率、房室传导功能以及迷走神经张力的关系。窦缓病人多径路检出率为50.98%,年龄越轻,基础窦性心率越慢、房室传导功能越差,其发生率越高。阿托品可使绝大多数病人的多径路传导消失,提示迷走神经张力过高引起的窦缓和房室传导功能降低可能是多径路传导发生的主要原因之一。

In order to investigate the occurrence of atrioventricular nodal multi-pathways in patients with sinus bradycardia. To observe the incidence of multi-pathways, and focus on its relationship with age, basic sinus heart rate, atrioventricular conduction and vagal tone. The detection rate of multi-pathways in patients with sinus bradycardia was 50.98%. The younger the patients, the slower the basal sinus rate and the worse the atrioventricular conduction function, the higher the incidence rate was. Atropine can lead to the disappearance of the multipath pathway in the vast majority of patients, suggesting that reduced vagal sinus and atrioventricular conduction caused by excessive vagal tone may be one of the major causes of multipath conduction.
