患者,女性,1岁。主因间断性面色苍白伴出冷汗,食欲减退三个月而入院。查体:心界不大,心率210次/分,律整,无杂音。心电图表现:P波规律出现,心室率250次/分,P-R间期0.08秒,QRS波群呈室上性,时限为0.06秒,Q-T间期0.18秒,T波在Ⅰ、Ⅱ、aVF导联低平。心电图诊断:阵发性房性心动过速。给予地高辛0.07mgl次/日治疗,15天后复查心电图,表现为:窦性P波规律出现,心室率97次/分,P-R间期0.16秒,QRS波群呈室上性,时限为0.08秒,Q-T间期0.40秒,在V_3导联P-R间隔相差>0.12秒,在V_5导联P-R间期缩短为0.08秒,R波起始部粗钝,似“δ”波,并继发ST-T改变。心电图诊断:窦性心律不齐伴阵发性预激综合征。
Patient, female, 1 year old. The main intermittent pale complexion with cold sweat, loss of appetite for three months and admitted to hospital. Physical examination: little heart, heart rate 210 beats / min, law, no noise. ECG showed: P wave law, ventricular rate of 250 beats / min, PR interval of 0.08 seconds, QRS complex was supraventricular tachycardia, the time limit of 0.06 seconds, QT interval of 0.18 seconds, T wave in Ⅰ, Ⅱ, aVF lead Low flat. ECG diagnosis: paroxysmal atrial tachycardia. Given digoxin 0.07mgl times / day treatment, 15 days after the review of ECG, showed: sinus P wave regularity, ventricular rate 97 beats / min, PR interval of 0.16 seconds, QRS complex was supraventricular, time limit of 0.08 Seconds, QT interval of 0.40 seconds, PR interval in V_3 lead> 0.12 seconds, PR interval in V_5 lead shortened to 0.08 seconds, R wave blunt start, like “δ” wave and secondary ST- T changed. ECG diagnosis: sinus arrhythmia with paroxysmal WPW syndrome.
