The anatomical substrate for AV nodal reentrant tachycardia (AVNRT) is well known and is due to anterograde conduction through a slow conducting pathway and retrograde conduction using a fast conducting pathway. In this report, we describe a patient with AVNRT who also presented with frequent episodes of paroxysmal nonreentrant tachycardia due to the occurrence of two conducted ventricular beats for each sinus depolarization. Palpitations and arrhythmias were abolished after radiofrequency ablation of the slow pathway.
房室结折返性心动过速（AVNRT）的解剖学基础已为人熟知，它是由于通过一条慢传导通路进行前向传导，并利用一条快传导通路进行逆向传导所致。在本报告中，我们描述了一名患有AVNRT的患者，该患者还因每次窦性去极化出现两次心室下传搏动而频繁发作阵发性非折返性心动过速。在对慢传导通路进行射频消融后，心悸和心律失常消失。
