食管心房调搏在小儿心动过速中的应用

Application of transesophageal atrial pacing in children tachycardia

目的探讨食管电生理检查对小儿心动过速的诊断、分型和终止发作的临床意义。方法采用食管心房调搏技术对３２例小儿快速心律失常进行分型诊断及转复治疗。结果心动过速３２例中体表心电图表现为室上性心动过速（室上速）２７例：其中房室折返性心动过速１５例，房室结折返...

Objective To study the significance of transesophageal electrophysiologic technique in determining the various mechanism and treatment of tachycardia in children.Methods Transesophageal artrial pacing(TEAP) was applied to the diagnosis and conversion of 32 children with tachycardia .Results 27 of 32 patients showed supraventricular tachycardia(SVT) on the electrocardiogram:AV reentry tachycardia in 15,AV node reentry tachycardia in 10,atrial reentry tachycardia in one and ectopic atrial tachycardia in one.One of 4 patients with atrial flutter(AF)were diagnosed as tachycardia-bradycardia syndrome.One patient with tachycardia source unknown was diagnosed as ventricular tachycardia by recording transesophageal eletrocadiogram.26 patients with SVT and 4 patients with AF were converted by TEAP.Chronic treatment of medicine in 8 patients with SVT proved effective by examination of TEAP.Conclusion TEAP is very important in determining various mechanisms and terminating tachycardia in pediatric patients.TEAP for acute conversion of any episode of SVT and AF in children is recommended.
