Shift in the retrograde atrial activation sequence after radiofrequency catheter ablation in left variant atypical atrioventricular nodal reentrant tachycardia

We describe an unusual case of “left-variant” atypical AVNRT, where change in the retrograde earliest atrial activation site (REAAS) at the coronary sinus (CS) following radiofrequency catheter ablation (RFCA) was observed. Our observation suggests that the REAAS, that is, the left AVN connections, could participate in the formation of the reentrant circuit of “left-variant” atypical AVNRT.
