周某,女,61岁。因慢性咳嗽、咯痰8年,气急1年,症状加重20天于1084年12月30日入院。临床诊断:慢性支气管炎、肺气肿,肺心病。 附图为V_1导联心电图。图中显示P波规律出现,形态一致,P-P间期为0.28秒,心房率为230次,为房性心动过速。QRs波群两个一组,其中前1个为qr型,时限0.08秒,是心室内正常传导,可疑右心室肥厚,第2个QRS波群呈rS型,(V_5相应的QRS波群亦为rS型),时限为0.10秒,提示第2个QRS波群是室内三位
Zhou, female, 61 years old. Chronic cough, expectoration 8 years, 1 year impatience, symptoms increased 20 days in December 30, 1084 admission. Clinical diagnosis: chronic bronchitis, emphysema, pulmonary heart disease. The figure is V_1 lead ECG. The figure shows the law of P wave appears, the same form, P-P interval of 0.28 seconds, atrial rate of 230 times, for atrial tachycardia. QRs group of two waves, of which the first one for the qr type, the time limit of 0.08 seconds, is normal ventricular conduction, suspected right ventricular hypertrophy, the second QRS complex was rS type (V_5 corresponding QRS complex also rS type), the time limit of 0.10 seconds, suggesting that the second QRS complex is the indoor three
