关于左房心律的心电图诊断标准还存在着争论.以往的标准是:(1)额面导联P波的平均电轴在+106°到+270°之间;(2)P_(I、V6)倒置;(3)P_(V?)双向或等电位;(4)心前导联P波呈“圆顶-尖峰”状(即前半部圆钝,后半部尖耸).本文报道左房性室上性心动过速患者电生理检查的结果.方法:5例药物不能控制的左房室上性心动过速患者,年龄自6岁至15岁,其中1例有法乐氏四
There are still controversies about the ECG diagnostic criteria of left atrial rhythm, which used to be: (1) the average electric axis of frontal plane P waves is between +106 ° and +270 °; (2) P_ (I, V6 ) Inverted; (3) P_ (V?) Bi-directional or equipotential; (4) P wave of the anterior P lead was “dome - spike ” (that is, the first half obtuse, the latter half sharp) Results of electrophysiological examination in patients with left atrial supraventricular tachycardia.Methods: Five patients with uncontrollable left atrium supraventricular tachycardia were aged from 6 to 15 years old. One patient had tetralogy
