Abstract

Focal atrial tachycardia arising from the right atrial appendage (RAAT) may be misdiagnosed as sinus tachycardia. The electrocardiogram from this case demonstrates a negative notched P-wave in leads V and V during RAAT compared with a beat of sinus rhythm. RAAT was confirmed and eliminated with mapping and ablation. ().

摘要

起源于右心耳的局灶性房性心动过速（RAAT）可能被误诊为窦性心动过速。该病例的心电图显示，与窦性心律的一次搏动相比，RAAT期间V1和V2导联出现负向切迹P波。通过标测和消融证实并消除了RAAT。（）
