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.
