本报告描述了在55个月的时间里,16例在他的束内出现阻滞的患者。女性10例,男性6例,平均年龄76岁,年龄范围42 ~ 98岁。所有患者的His束记录均显示His束电位(H和H)分裂(13例)或QRS狭窄伴远端His束电位阻滞(3例)。16例患者中,10例为完全性心脏传导阻滞,4例为二级房室传导阻滞(2例为Mobitz II型,2例为2:1),2例为一级房室传导阻滞。10例患者在传导节拍或逃逸节奏中QRS狭窄。静脉注射阿托品(1 ~ 2mg)对房室传导和逸出节律率有不同的影响。12名患者植入了永久性心脏起搏器。随访期间,10例患者在初检后1 ~ 31个月死亡。其余6例患者(5例使用起搏器)存活3 - 58个月。
This report describes 16 patients with block within the His bundle seen over a period of 55 months. Ten were women and 6 men, with an average age of 76 years, range, 42 to 98 years. All patients had His bundle recordings showing split His bundle potentials (H and H) (13 patients) or narrow QRS with block distal to the His bundle potential (3 patients). Of the 16 patients, 10 had complete heart block, 4 second degree AV block (2 patients with Mobitz type II, and 2 with 2:1), and 2 first degree AV block. Ten patients had a narrow QRS in the conducted beats or escape rhythms. Intravenous atropine (1 to 2 mg) had a variable effect on AV conduction and the rate of the escape rhythm. Twelve patients have had a permanent pacemaker implanted. During the follow-up period, 10 patients died 1 to 31 months from the time of initial examination. The remaining 6 patients (5 with pacemaker) are alive 3 to 58 months later.
