Atrioventricular Re-entry Tachycardia (AVRT) is a form of paroxysmal supraventricular tachycardia that occurs in patients with accessory pathways, usually due to formation of a re-entry circuit between the AV node and accessory pathway. ECG features depend on the direction of conduction, which can be orthodromic or antidromic.

Atrioventricular reentrant tachycardia (AVRT), or atrioventricular reciprocating tachycardia, is a type of heart arrhythmia with an abnormally fast rhythm (tachycardia); it is classified as a type of supraventricular tachycardia (SVT).

2019年9月26日 · 折返性室上性心动过速最常见的两种类型是 AVRT 和 AVNRT，这是一对长得很像的孪生兄弟：名称上只差一个字母，心率通常都在 150～250bpm，可见到窄 QRS 心动过速，刺激迷走神经可打断折返使室上速终止，呈突发突止的特点。 但既然两兄弟不是同一个人，就总有不一样的地方。 那么他们的区别在哪里？ 体表心电图应该如何区分？ 怀着共同学习的心态，下面给大家分享一些我对区分室上性心动过速的小想法。 首先不得不提的是这两兄弟的共同原理： …

房室折返性心动过速（AVRT）的发生率仅次于 房室结折返性心动过速 （AVNRT），约占全部室上性心动过速的30%。 患者可有心悸、心前区不适或 心绞痛 、 眩晕，严重时可有血压降低、 休克 及心功能不全。 隐匿性旁路参与的AVRT的发病率尚不明确。 隐匿性旁路参与的AVRT患者从儿童到老年人均有发生，年轻者更多一些。 年轻患者常不伴有器质性 心脏病，年长患者可伴有各种器质性 心脏病。 大部分 预激综合征 伴发AVRT患者临床无器质性 心脏病 依据，小部分患者可 …

Individuals with accessory pathways are at risk of developing atrioventricular reentrant tachycardia (AVRT). This is a rapid tachyarrhythmia in which a macroscopic re-entry circuit involves the atria, atrioventricular node, accessory pathway and the ventricles. In most cases, the re-entry is induced by a premature atrial beat.
