预激综合症(WPW)是由于房室纤维环与先天性肌性短路旁道相连,结果使房室传导速度加快而引起的。这些纤维形成的解剖异常,是导致折返性心动过速和阵发性室上性心动过速(SVT)的基础。作者报告一例病人在围术期出现SVT经各种药物治疗、颈动脉窦按摩以及电复律无效,改用新福林而获得缓解。此例男、17岁(55kg),行双侧斜视矫正术。病人患预激综合症合并阵发性SVT和有规律发作折返性心动过速史5年,往往因劳累和过度兴奋诱发,用异搏定和按摩颈动脉窦能使症状消失。 Wolff-Parkinson-White syndrome (WPW) is due to atrioventricular annulus fibrosis and congenital muscular short circuit connected to the results of the atrioventricular conduction speed caused. The anatomic abnormalities that these fibers form are the basis for reentrant tachycardia and paroxysmal supraventricular tachycardia (SVT). The authors report that in one patient with SVT during perioperative period, various drug treatments, carotid sinus massage, and electrical cardioversion were ineffective and were switched to neo-forrest. This case of male, 17 years old (55kg), line bilateral strabismus surgery. Patients with pre-excitation syndrome with paroxysmal SVT and regular episodes of reentrant tachycardia for 5 years, often induced by overwork and overwork, with verapamil and massage the carotid sinus can make the symptoms disappear.
