束支传导阻滞表现为双向文氏周期者较少见,最近我们遇到1例,报道如下。患者男性,83岁,因慢性咳嗽、咳痰4年症状加重伴畏寒、发热7d于1989年2月19日入院。经检查诊断为:慢性支气管炎伴肺部感染。附图为动态心电图V_1导联连续记录:窦性P波规则出现,P-P间距0.50s,心率120次/min,P-R间期固定0.16s,R-R间期也固定为0.50s。QRS波群呈两组规律性变化:①上行QRS_(1、6、12)呈rs形(QRS时间0.07s),QRS_(2-7)呈rsR’形,但其形态
Bunch branch block showed two-way Wen’s cycle is rare, we recently encountered a case reported below. Male patient, 83 years old, due to chronic cough, sputum 4 years of aggravated symptoms with chills, fever 7d on February 19, 1989 admission. After examination, diagnosed as: chronic bronchitis with pulmonary infection. The figure for the Holter continuous recording V_1 lead: sinus P wave rules appear, P-P spacing 0.50s, heart rate 120 beats / min, P-R interval fixed 0.16s, R-R interval is also fixed at 0.50s. There were two regular changes in QRS complex: (1) QRS (1, 6, 12) was rs-shaped (QRS time was 0.07s); QRS_ (2-7)
