临床资料 患男,77岁,临床诊断为慢性支气管炎;阻塞性肺气肿;慢性肺原性心脏病;高血压病;心力衰竭。 心电图特征 1989年1月21日记录的心电图为窦性心律及异位心律。电轴+90°,P—R间期0.18s,窦性R—R间期0.58s频率103次/minV_1呈rSR’,R’高达2.2mV,I、aVL、V_4—6导联均有宽S波,S_(v5)深1.lmV。另各导联见散在性以早搏形式出现的室性搏动,亦似完全性右束支阻滞型,仅其振幅较窦性QRS为高。联律间期变动于0.36—0.52s。各个长异位R—R间期均为短异位R—R间期的简单整数倍(见图Ⅱ导联)。R’_2、R’_4和R’_6为室性融合波。说
Clinical data Male, 77 years old, clinical diagnosis of chronic bronchitis; obstructive emphysema; chronic pulmonary heart disease; hypertension; heart failure. ECG characteristics January 21, 1989 ECG recorded as sinus rhythm and ectopic rhythm. The electrical axis + 90 °, P-R interval 0.18s, sinus R-R interval 0.58s frequency 103 times / minV_1 rSR ’, R’ as high as 2.2mV, I, aVL, V_4-6 leads are wide S wave, S_ (v5) deep 1.lmV. The other lead see scattered in the form of premature ventricular beats in the form of ventricular tachycardia, also seems completely right bundle branch block type, only the amplitude of sinus QRS is higher. Associated law between the period of 0.36-0.52s. The R-R interval of each long heterostere is a simple integer multiple of the short ectopic R-R interval (see Figure II lead). R’_2, R’_4 and R’_6 are ventricular fusion waves. Say
