A short PR interval, a delta wave, and attacks of paroxysmal tachycardia are the principal features of the WPW syndrome. A grossly irregular rhythm with bizzare QRS complexes at rates exceeding 180 per minute is one of the paroxysmal tachycardias characteristic of the WPW syndrome. This arrhythmia deserves special attention, because it is often misinterpretated as ventricular tachycardia. The interpretation is atrial fibrillation with varying degrees of ventricular fusion and phasic ventricular aberration. Prompt electrical cardioversion is indicated because, at times, ventricular fibrillation may result. Quinidine sulfate used prophylactically because of its negative dromotropic effect on the accessory pathway promotes A-V transmission via the A-V node.
短PR间期、δ波和阵发性心动过速发作是预激综合征的主要特征。WPW综合征特征性的阵发性心动过速之一是心率超过每分钟180次时出现的极不规则节律和奇异的QRS波群。这种心律失常值得特别关注，因为它常被误诊为室性心动过速。其诊断为伴有不同程度心室融合和间歇性心室差异传导的心房颤动。由于有时可能会导致心室颤动，所以应立即进行电复律。硫酸奎尼丁因其对旁路有负性传导作用而用于预防，可促进房室结的房室传导。
