室上性心动过速常为阵发性,突然发生和突然停止,为临床上常见心律紊乱之一,无论有否器质性心脏病均可发生。常为房性早搏和/或室性早搏所诱发,除合并束支传导阻滞者外,一般 QRS 综合波形态正常,R—R 之间期规则。刺激迷走神经常可终止发作。其发病机理多数系由于折返所致,少数亦可由于自律性增高引起。本文着重讨论室上性心动过速的分类、诊断和处理要点。一、房室结折返性心动过速室上性心动过速中,由于房室结折返引起的较为常见,它可分为慢—快和快— Supraventricular tachycardia often paroxysmal, sudden and sudden stop, one of the common clinical rhythm disorders, whether or not organic disease can occur. Often atrial premature beats and / or ventricular premature be induced, in addition to combined with bundle branch block, general QRS complex wave morphology, R-R interval rules. To stimulate the vagus nerve can often terminate the attack. Most of its pathogenesis due to reentry due to a small number may also be due to increased self-discipline. This article focuses on the classification, diagnosis and treatment of supraventricular tachycardia. First, atrioventricular nodal reentrant tachycardia Supraventricular tachycardia, due to atrioventricular nodus caused by the more common, it can be divided into slow - fast and fast -
