经心内希氏束图记录证实的各类房室传导阻滞症30例。9例希氏束内或希氏束远端Ⅰ°阻滞者,心电图有P-R延长者只2例,4例有昏厥史。说明希氏束内或希氏束远端Ⅰ°阻滞常规心电图难以发现。建议对房室传导阻滞伴昏厥患者、昏厥原因不明者、左束支阻滞及疑有双侧束支阻滞的患者在有条件时进行心内希氏束图记录,有利于估计预后,安排治疗。
30 cases of various types of atrioventricular block confirmed by intracardiac His bundle recording. 9 cases of His bundle or His bundle distal I ° block, electrocardiogram P-R extension in only 2 cases, 4 cases have a history of syncope. Description His bundle or His bundle distal I ° block conventional ECG difficult to find. Recommendations for patients with atrioventricular block and fainting, unexplained fainting, left bundle branch block and suspected bilateral bundle branch block in patients with intrauterine magnetic resonance imaging under the conditions of the beam map is conducive to the estimation of prognosis, Arrange treatment.
