预激综合征 (wolff-parkinsonwhite syndrome,简称w-P-W综合征)最重要的临床意义是伴发室上性快速型心律失常。其中主要为阵发性室上性心动过速,其次为快速心室率的心房颤动或心房扑动。发作时如未及时控制,有可能导致心搏血量降低,甚至诱发室颤而死亡。因此,对预激综合征伴发快速型异位心律的诊断及其处理是临床工作中一个重要的问 Wolff-parkinsonwhite syndrome (W-P-W syndrome for short) the most important clinical significance is associated with supraventricular tachyarrhythmia. Among them were paroxysmal supraventricular tachycardia, followed by rapid ventricular rate atrial fibrillation or atrial flutter. If not timely control of seizures, may lead to reduced cardiac blood volume, and even induce ventricular fibrillation and death. Therefore, the WPW syndrome with rapid ectopic rhythm diagnosis and treatment is an important clinical work
