Atrioventricular nodal reentry tachycardia is a supraventricular tachycardia with a double nodal pathway between the atria and the ventricles located in the normal AV-node. It may cause a reentry circuit. Atrioventricular nodal reentry tachycardia is one of the most common supraventricular tachycardias in adulthood, but is seldom diagnosed in children--perhaps because of difficulties with diagnosing them. We have studied diagnostic criteria, clinical presentation, incidence, prognosis and treatment in children and adolescents.
The article is based on the literature found in the databases PubMed and Medline. We used the search words atrioventricular nodal reentry tachycardia, AVNRT, permanent junctional reentry tachycardia, PJRT, supraventricular tachycardia, neonates, infants and children. Articles were also identified by examining the references.
Atrioventricular nodal reentry tachycardia is rare during the first years of life, but becomes more frequent with age. There are few studies of this rhythm disturbance in children and reliable data on incidence, prognosis and prognostic variables are limited, especially for untreated cases. There are three main treatment regimens, acute and prophylactic medication and curative treatment with radiofrequency catheter ablation.
房室结折返性心动过速是一种室上性心动过速，在位于正常房室结内的心房和心室之间存在双结径路，可导致折返环路。房室结折返性心动过速是成年期最常见的室上性心动过速之一，但在儿童中很少被诊断出来——这可能是因为诊断存在困难。我们对儿童和青少年的诊断标准、临床表现、发病率、预后及治疗进行了研究。
本文基于在PubMed和Medline数据库中检索到的文献。我们使用了“房室结折返性心动过速”“AVNRT”“持续性交界性折返性心动过速”“PJRT”“室上性心动过速”“新生儿”“婴儿”和“儿童”等检索词。还通过查阅参考文献来识别文章。
房室结折返性心动过速在生命的最初几年很少见，但随着年龄增长会变得更为常见。关于儿童这种心律失常的研究较少，关于发病率、预后及预后变量的可靠数据有限，尤其是对于未经治疗的病例。有三种主要的治疗方案，即急性和预防性药物治疗以及射频导管消融根治性治疗。
