除窦性心动过速和心房纤颤外,需鉴别的 QRS波群不增宽(∠0.08秒)的心动过速有房速、房扑、房室结性心动过速、经房室附加束逆行运导的环形运动性心动过速和少数由附加旁路缓慢逆行传导的持续性心动过速。因为治疗不同,鉴别各类心动过速就成为一个重要课题。电生理检查虽然是最好的诊断方法,但尚不能普遍开展。作者通过电生理研究,分析了 QRS 波群不增宽的心动过速时十二导联心电图的特点,提出了诊断心动过速激动起源点的五项体表心电图标准:(1)P 波的位置;(2)P 波电轴;(3)心房率;(4)有无 QRS 波群交替性变化;(5)房律和室律的关系。用心脏程序刺激法对187例
In addition to sinus tachycardia and atrial fibrillation, the QRS complex to be identified is not widened (∠ 0.08 seconds) tachycardia with atrial tachycardia, atrial flutter, atrioventricular tachycardia, extra-atrioventricular bundle Circulatory tachyarrhythmias with retrograde conductance and a few persistent tachycardias that are retrogradely retrograde with additional bypass. Because of the different treatment, identification of various types of tachycardia has become an important issue. Although electrophysiological examination is the best diagnostic method, it can not be carried out universally. Based on the electrophysiological studies, we analyzed the characteristics of 12-lead electrocardiogram (ECG) when the QRS wave group did not broaden, and proposed five surface ECG criteria for the diagnosis of the origin of tachycardia (1) P wave Position; (2) P-wave axis; (3) atrial rate; (4) whether there is an alternation of QRS complex; (5) atrial and ventricular rhythm. 187 cases of cardiac program stimulation
