Clinical Application of Transvanous Implantable Cardioverter Defibillator

Objective:To observe the clinical effect of ICD(implantable cardioverter-defibrillator, ICD) in seven patients.Methods: The data of seven patients who had successful implantation ICD in the hospital from July 1996 to September 2003 were reviewed retrospectively.In these patients, four were dilated cardiomyopathy; one was long QT syndrome; one was pleomorphism ventriculary tachycardia;one was right bundly branch block accompany serious ventricular arrhythmia(may be Brugada syndrome).All episodes of VT and/or VF had been recorded, five patients had history of syncope.All patients were followed-up for an average of 2.3 years.Results: All patients had sucessful implantation ICD system in Cath Lab.The Defibrillation threshold was less than 25 J.In follow-up,there were sixteen episodes of ventriculary tachyarrhythmia(ten episodes of VT; six episodes of VF) and ten episods of VT which were terminated by antitachycardia pacing (ATP) and had six episodes of VF which were terminated by difibrillation.There were four anti-tachyarrhythmia pacing for mistaken sensed sinus tachycardia and two defibrillation for mistaken sensed supraventricular.All patients survived.Conclusion: Implantation of ICD is an safe effective approach to treat ventricular arrhythmias in patients with structural heart diseases, but we should adjust parameter in time and strengthen follow-up and give drug as assist therapy.
