The main tool for the differentiation of supraventricular tachycardia is the 12-lead electrocardiogram (ECG). Especially differentiating the atrioventricular nodal reentrant tachycardia (AVNRT) from the atrioventricular reentrant tachycardia (AVRT) due to concealed accessory pathway or from an atrial tachycardia (AT) is very important for catheter setting and ablation approach in an electrophysiological study. In our case we saw the occurrence of a U wave during tachycardia-simulating a pseudo P wave. This mimicked a long RP-tachycardia, although it was a common type AVNRT.
鉴别室上性心动过速的主要工具是12导联心电图（ECG）。在电生理研究中，尤其重要的是将房室结折返性心动过速（AVNRT）与隐匿性旁路所致的房室折返性心动过速（AVRT）或房性心动过速（AT）区分开来，这对于导管置入和消融方法至关重要。在我们的病例中，我们观察到心动过速期间出现U波——模拟假性P波。尽管这是一种常见类型的AVNRT，但它模拟了长RP心动过速。
