临床资料患者宋某,女,33岁。因心慌、气喘、反复发作3年加重2天急诊入院。临床诊断:风湿性心脏病,二尖瓣狭窄,二尖瓣闭锁不全。心律失常。病态窦房结综合征。心电图特征连续描记Ⅱ导联示: 第2个P波为正常下传的窦性激动。第1个P波到第2个P波的P—P间期为0.88″,以后的P—P间期基本上有逐渐缩短的文氏周期,长间歇比2个窦性周期(0.88″)之和短,属Ⅱ度Ⅰ型窦房阻滞。图中段出现短阵性房性阵速,其P—P间期为0.33″,频率200次/分。第1、3、4、6、7、8、9、11、12、14、15、17、18、20等QRS波为交界性逸博,QRS波形态与基本心动一致。逸博的R—R间期最
Patients with clinical data Song, female, 33 years old. Due to palpitation, asthma, recurrent 3-year exacerbation 2 days emergency admission. Clinical diagnosis: rheumatic heart disease, mitral stenosis, mitral regurgitation. Arrhythmia. Sick sinus syndrome. Continuous electrocardiographic tracing Ⅱ lead shows: the first two P-wave for the normal transmission of sinus stimulation. The first P-wave to the second P-wave had a P-P interval of 0.88 “and the subsequent P-P interval had essentially a shortened Wen’s cycle and a longer interval than the two sinus cycles (0.88” And short, is a degree Ⅱ Ⅰ type sinus block. The middle part of the figure showed a short array of atrial fibrillation, the P-P interval was 0.33 ", the frequency of 200 beats / min. The first 1,3,4,6,7,8,9,11,12,14,15, 17, 18, 20 and other QRS waves are borderline esophageal, QRS wave morphology consistent with the basic heart. Yi Bo’s R-R interval
