预激综合征的发生率为0.5%～2.0%,此病的患者中约有50%～70%合并有反复发作性心动过速。11.5%～39%可并发房颤。其特点为心室率甚快,可达200～360次/分,对发病者的血液动力学影响很大。持续时间过久可发生休克,心力衰竭,甚至导致猝死。本组病人2例患有器质性心脏病,1例为非器质性心脏病。3例均为反复发作性预激综合征合并 The incidence of WPW syndrome is 0.5% to 2.0%. About 50% to 70% of patients with this disease have recurrent tachycardia. 11.5% ~ 39% can be complicated by atrial fibrillation. It is characterized by very fast ventricular rate, up to 200 ~ 360 beats / min, the hemodynamic impact of those who have a great impact. The duration of shock can occur too long, heart failure, and even lead to sudden death. Two patients in this group had organic heart disease and one had non-organic heart disease. 3 cases were recurrent Wolff-Parkinson’s syndrome
