右侧间隔旁路中以希氏束上、下0.5cm以内的旁路射频消融时易产生希氏束损伤及影响房室传导,应密切观察消融过程中的结性逸搏,及时观察P-R间期变化,以避免并发房室传导障碍。
On the right side of the bypass in order to His bundle, within the next 0.5cm bypass radiofrequency ablation tend to produce His bundle injury and affect atrioventricular conduction should be closely observed during ablation yoke, the timely observation of PR Period changes to avoid concurrent Atrioventricular Barriers.
