Reported here are 162 cases of atrial ectopic tachycardia, a specific type of the supraventricular arrhythmia, which is characterized by the distinct P waves on the ECG, which follow at the rate of 400 and more per minute. Although atrial ectopic tachycardia is similar to the supraventricular paroxysmal tachycardia and atrial flutter, it differs from them by the mechanism of the development. Atrial ectopic tachycardia is caused by the failure or weakening the sinus node and the appearance of the ectopic focus in the atria. Such arrhythmia occurs in the following 4 types: with atrial to ventricular excitation ratio 1:1; with incomplete atrio-ventricular block; with complete atrioventricular block; and in combination with atrial fibrillation. Atrial ectopic tachycardia often takes lingering course and is hardly responsive to the medical treatment. The cases of arrhythmia, characterized by the broad P waves on the ECG tend to the progressive course. 17 cases of atrial ectopic tachycardia treated by electrostimulation (ES) which had 100% positive effect are presented and ES advantages over the drug therapy are underlined. The frequent transition of this arrhythmia into the atrial fibrillation is outlined.
本文报道了162例房性异位性心动过速，这是室上性心律失常的一种特殊类型，其特征是心电图上有明显的P波，每分钟频率达400次及以上。虽然房性异位性心动过速与室上性阵发性心动过速和心房扑动相似，但在发病机制上有所不同。房性异位性心动过速是由窦房结功能衰竭或减弱以及心房异位起搏点的出现引起的。这种心律失常有以下4种类型：房室激动比例为1:1；伴有不完全性房室传导阻滞；伴有完全性房室传导阻滞；以及合并心房颤动。房性异位性心动过速病程往往迁延，药物治疗效果不佳。心电图表现为宽大P波的心律失常病例往往呈进行性病程。本文介绍了17例经电刺激（ES）治疗且效果100%阳性的房性异位性心动过速病例，并强调了ES相对于药物治疗的优势。概述了这种心律失常频繁转变为心房颤动的情况。
