心动过速后综合征是MeMilan和Bellet在1931年首次提出的,它包括心动过速后暂时性T波低平和倒置,ST段下移和Q-T间期延长也可以存在。本文作者报告2例,其心电图改变是短时间的,其本身并不指示有基础的心脏病。2例患儿皆为新生儿。1例为14天女婴,心电图显示260次/分的房性阵发性心动过速,在插入静脉线路后转为窦性心律,心电图示右房增大,预缴综合征(A型),V_1～V_6导联T波倒置,Q-T和矫正Q-T间期分别为0.44和0.46秒,患儿应用了洋地黄,数天后右胸前导联T波变为直立,ST段下移恢复。另一例出生后很快发现呼吸急
Post-tachycardia syndrome, first proposed by MeMilan and Bellet in 1931, includes temporary flattening and inversion of the T-wave after tachycardia, extension of the ST segment, and prolongation of the Q-T interval. The authors report 2 cases of ECG changes is a short time, which itself does not indicate a basic heart disease. 2 cases of newborns are all children. One case was a 14-day-old female with electrocardiogram showing 260 episodes / minute of paroxysmal atrial tachycardia, switched to sinus rhythm after insertion of the intravenous route, electrocardiogram showed right atrial enlargement, prepayment syndrome (type A) T wave of V_1 ~ V_6 lead was inverted, and QT and corrected QT interval were 0.44 and 0.46 seconds respectively. Digitalis was applied in children. T wave in right thoracic duct turned upright and recovered in ST segment after a few days. Another example soon found breathing after birth
