室上性心动过速(Supraventricular tachycardia),简称室上速,亦属室上性快速心律失常,包括窦性心动过速、阵发性房性和房室交界性心动过速、房扑、房颤、阵发性房性心动过速伴房室阻滞、多源性房性心动过速及予激征候群。室上速为临床上常见的一组心律失常,可以发生在有或无心脏病的病人,其特点为(?)发性,突然发作,突然终止,心率无渐增现象,其频率一般150～220次/分,通常房年或室性早搏均可诱发。为了便于指导临床,本文着重讨论室上速的简要发病机理及治疗进展。 Supraventricular tachycardia, referred to as supraventricular tachycardia, is also supraventricular tachyarrhythmias, including sinus tachycardia, paroxysmal atrioventricular and atrioventricular tachycardia, atrial flutter, room Tremor, paroxysmal atrial tachycardia with atrioventricular block, multi-source atrial tachycardia and irritable signs. Supraventricularism is clinically common in a group of arrhythmias, can occur in patients with or without heart disease, which is characterized by (?) Hair, sudden onset, abrupt termination, no gradual increase in heart rate, the frequency of 150 to 220 Times / min, usually atrial or ventricular premature be induced. In order to facilitate the guidance of clinical, this article focuses on the brief pathogenesis of supraventricular tachycardia and treatment progress.
