Focal Atrial Tachycardia Originating From the Right Atrial Appendage Masquerading as Inappropriate Sinus Tachycardia

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(1) and V(2) during RAAT compared with a beat of sinus rhythm. RAAT was confirmed and eliminated wit...

Sumario: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(1) and V(2) during RAAT compared with a beat of sinus rhythm. RAAT was confirmed and eliminated with mapping and ablation. (Level of Difficulty: Advanced.)
