Abstract Objective To report the clinical anti-arrhythmic effectiveness of implantable cardioverter defibrillator (ICD) in 13 cases.Methods Among the 13 cases, 10 were implanted with unicamerata ICD while 3 with dual-chambered ICD. Make enquirements by telephone and carry out follow-ups in out-patient clinic in order to analyse conditions of the patients and the working state of ICD, through electrocardiogram, dynamic electrocardiogram and the data stored in ICD.Results Sustainable ventricular tachycardia(VT) or ventricular fibrillation(VF) attacks 38 times in all(sustainable VT 36 times, VF twice), 37 times of which were successfully conversed and yet one time failed.Nonsustainable VT happens 121 times and the attacks all ceased by themselves.The sustained VT was rapid conversed by ICD in ATP(anti-tachycardia pacing) mode for 33 times and low-energy conversion(CV) twice.But once, it progressed to VF during the ICD treatment and was terminated by high-energy defibrillation(DF).The high ventricular rate followed by paroxysmal atrial fibrillation was misidentificated as VT twice in one case and ATP treatments were delivered by ICD. The ventricular arrhythmia storms appeared in one case 3 months after the implantation.Three patients needed to take Amiodarone and (or) Metoprolol because of recurrent attack of VT. The doses should be adjusted according to the severity of arhythmia.Conclusion To improve the effectiveness of ICD implanted, followed-ups should be strengthened and working parameters should be adjusted in time.Meanwhile, psychological intervention also plays an important role.
