Abstract: Objective The explore resuscitation and nursing of ventricular fibrillation (VF)during the ablation of idiopathic left ventricular tachycardia (ILVT).Methods Radiofre-quency ablation guided by 3-D mapping system treated for ILVT.During the procedure,the de-fibrillator,the patches and the ventilator should be prepared.Results VF happened in 5 patients during ablation,and the resuscitation was successful after defibrillation and countermeasures.Con-clusion electrocardiograph monitoring,fully preparation before operation,active resuscitation and nursing countermeasures are the key to the success during the radiofrequency ablation.
