患者,男,21岁。无自觉症状,1975年12月11日体检时发现心率较快,心电图示间歇性完全性右束支传导阻滞伴右心室肥大。图1系同一次描记的V_1、V_3、V_5及Ⅱ导联心电图。导联Ⅱ下面梯形图解自上而下分别代表心房、房室交界组织、束支和心室,数字表示P—P及R—R间隔时间,均以1/100秒计。V_1的QRS综合波呈rsR′型,R′高达2.2毫伏;V_5呈qR_S型,S波宽大; QRS时限0.12秒;为典型的完全性右束支传导阻滞图形伴右心室肥大。V_3 QRS综合波呈RS型,时限0.08秒,系正常的心室内传导。在导联Ⅱ中第1、2、3、7、8、9、10、10心搏呈完全
Patient, male, 21 years old. No symptoms, December 11, 1975 physical examination found that heart rate, ECG showed intermittent right bundle branch block with right ventricular hypertrophy. Figure 1 Department of the same trace V_1, V_3, V_5 and Ⅱ lead ECG. Lead below the ladder diagram from top to bottom, respectively, on behalf of the atrium, atrioventricular junction, bundle branch and ventricular, digital P-P and R-R interval, both in 1/100 seconds. The QRS complex of V_1 was rsR ’and R’ was 2.2 mV. V_5 was qR_S and S wave was broad. The QRS duration was 0.12 seconds. It was a typical complete right bundle branch block with right ventricular hypertrophy. V_3 QRS complex was RS type, the time limit of 0.08 seconds, Department of normal ventricular conduction. In the lead Ⅱ 1,2,3,7,8,9,10,10 heart beats completely
