室上性心动过速是一种临床上常见的心律失常,可发生于心脏病和非心脏病病人,其特点是阵发性发作,即突然开始,突然终止,没有速率逐渐增快的过程,速率通常是159～220次/分。房性和/或室性早搏通常可诱发其发作。心动过速时,RR 间期规则,除非有束支阻滞否则 QRS 波时限正常。若能发现 P波,则其形态与窦性 P 波不同,而且可发生于QRS 波之前、之后或同时。刺激迷走神经的方法往往可终止心动过速。在大多数病人心动过速的机理是折返,而在某些病人可能是由于自律性增高。本综述旨在讨论室上性心动过速的分类、诊断和处理。房室结折返性心动过速
Supraventricular tachycardia is a clinically common arrhythmia can occur in patients with heart disease and non-heart disease, which is characterized by paroxysmal attacks, that is, a sudden start, abrupt termination, there is no rate of gradual increase in the process, Rate is usually 159 to 220 beats / min. Atrial and / or ventricular premature beats usually induce seizures. Tachycardia, RR interval rules, unless there is a bundle branch block or QRS wave duration normal. If P wave can be found, its morphology and sinus P wave is different, and can occur before, after or at the same time QRS wave. Vagal stimulation of the way often to terminate tachycardia. The mechanism of tachycardia in most patients is reentry, and in some patients it may be due to increased self-discipline. This review aims to discuss the classification, diagnosis and management of supraventricular tachycardia. Atrioventricular nodal reentrant tachycardia
