Popis: | A 66-year-old man underwent a second ablation for atrial fibrillation (AF). Intravenous isoproterenol administration caused the atrial premature beat (APB), triggering AF. The APB originated in the right atrium and invariably initiated AF. Therefore, contact activation mapping could not be performed without frequent electrocardioversion. To prevent the initiation of AF without inhibiting the APB firing, we administered nifekalant intravenously, which facilitated precise activation mapping and ablation of the AF-triggering APB. The administration of nifekalant may improve clinical outcomes of catheter ablation for AF triggered by non-pulmonary vein APB, which invariably initiates AF. |
