Figure 1: Supraventricular tachycardia of the patient at the
emergency department.
Figure 2 : Intracardiac echocardiogram during the
electrophysiology study and ablation. Panel A Intracardiac
echocardiogram of the AT with AV 2 to 1 conduction and preexcitation.
Panel B 12 leads ECG of the AT. Panel C ventricular pacing with
eccentric atrial activation.Panel D intracardiac signal at the
successful ablation site for the accessory pathway
Figure 3: ECG during the ablation procedure. Panel A
Ventricular fibrillation during ablation Panel B Sinus rhythm with ST
interval elevation in the V1-V3 and inferior leads. Panel C Sinus rhythm
with preexcitation before ablation. Panel D Sinus rhythm without
preexcitation after ablation. Panel E Fluoroscopic view of the ablation
site. Panel F Coronary angiogram of the left coronary in correlation
with the ablation site.
