预激综合征是心房的激动沿正常传导系统下传尚未到心室肌之前附加房室传导,旁路预先地激动心室肌的一种综合征。预激综合征患者约11%～39%可并发心房颤动。其附加通道没有生理性延迟传导的保护作用,其不应期不随心率增快而变化,使心室率达180～300次/min,R-R<180ms,易诱发房颤。同时,心室激动经房室旁道逆传入心房,恰逢心房肌的易损期,而引起房颤或折返性心动过速,演变为房颤。预激综合征是一种少见的心率失常,预激综合征并发房颤更为心血管病急症。预激综合征并发房颤的诊断主要靠心电图,治疗要用抗心律失常药物。
Wolff-Parkinson-White syndrome is a syndrome of atrial activation that bypasses the pre-excitation of ventricular muscle by pre-attachment atrioventricular conduction before it is delivered to the ventricular muscle along a normal conduction system. About 11% to 39% of patients with WPW syndrome can be complicated by atrial fibrillation. The additional channel without physiological delay conduction protection, the refractory period does not change with the heart rate, the ventricular rate of 180 to 300 beats / min, R-R <180ms, easy to induce atrial fibrillation. At the same time, ventricular activation by atrioventricular retrograde afferent into the atrium, coincides with the atrial constriction, and cause atrial fibrillation or reentry tachycardia, evolved into atrial fibrillation. Wolff-Parkinson-White syndrome is a rare arrhythmia, Wolff-Parkinson-White syndrome is associated with atrial fibrillation more acute cardiovascular disease. The diagnosis of Wolff-Parkinson-White syndrome with atrial fibrillation depends mainly on ECG, treatment with anti-arrhythmic drugs.
