患者性,70岁。因畏寒、发热伴胸部不适1d,于1997年7月16日入院,20:25时床边急查心电图示(见附图):各导联除提前发生之P′波外,见窦性P波规则出现,心率91次/min,P-R不固定,P-R≤0.12s,R-R相等,QRS时限0.08s,心率亦为91次/min,以aVR为例进行分析:第1、第6～11个QRS波其P-R缩短为0.08～0.11s,P波与QRS波无关呈房室分离,第2、3QRS波前P波形态呈直主或低平,为窦性P波与交接区逆行的P~-波形成的房性融合波、
Patient sex, 70 years old. Due to chills, fever with chest discomfort 1d, admitted to hospital on July 16, 1997, 20:25 ECG emergency bedside map (see photo): in addition to the lead before the P ’wave, see sinus P wave rules appear, heart rate 91 beats / min, PR is not fixed, PR ≤ 0.12s, RR is equal, QRS duration 0.08s, heart rate is 91 beats / min, aVR as an example analysis: 1st, 6-11 A QRS wave PR reduced to 0.08 ~ 0.11s, P wave and QRS wave independent of atrioventricular separation, the first and second QQ wavefront P wave morphology was dominated or low, for the sinus P wave and the junction of the retrograde P ~ - Wave formation of atrial fusion wave,
