Objective To explore the outcome of patients with Brugada syndrome by remedial or prophylactic implantable cardioverter defibrillator(ICD)for ventricular tachyarrhythmia.Methods Sixteen single chamber ICDs and 5 double chamber ICDs in 21 consecutive patients [17 males,4 females;mean age,(36±11)years] with Brugada syndrome were involved.Fifteen patients with spontaneous or induced ventricular tachycardia/ventricular fibrillation(VT/VF)received the remedial and prophylactic ICD implantation.Six patients only with positive family history or syncope accepted the ICD implantation for prophylaxis.Results After a median follow-up of(22.3±13.4)months,all patients were alive.One patient was suspected with febrile syndrome due to endocarditis on the auricular face of the lead of defibrillator 18 months after ICD implantation and disappearance of vegetation was found after receiving one-month antibiotic treatment.Nine appropriate ICD interventions took place in 3 individuals with documented spontaneous ventricular arrhythmias.Multivariable analysis suggested that occurrence of appropriate interventions was related to the spontaneous ventricular arrhythmias(P<0.0001).Eleven inappropriate ICD interventions occurred in 3 patients for atrial fibrillation or atrial flutter with rapid ventricular rate.Multivariable analysis suggested that occurrence of inappropriate interventions was related to documented spontaneous supraventricular arrhythmias(P<0.0062).All appropriate interventions and inappropriate interventions occurred within six months after ICD implantation.Conclusion Appropriate interventions may associate to spontaneous ventricular arrhythmias before ICD implantation in patients with Brugada syndrome.Patients may suffer from inappropriate ICD intervention for supraventricular arrhythmias with rapid ventricular rate when they had a history of supraventricular arrhythmias.
Objective To explore the outcome of patients with Brugada syndrome by remedial or prophylactic implantable cardioverter defibrillator （ ICD ） for ventricular tachyarrhythmia. Methods Sixteen single chamber ICDs and 5 double chamber ICDs in 21 consecutive patients [ 17 males, 4 females; mean age, （ 36 ± 11） years ] with Brugada syndrome were involved. Fifteen patients with spontaneous or induced ventricular tachycardia/ventricular fibrillation （VT/VF） received the remedial and prophylactic ICD implantation. Six patients only with positive family history or syncope accepted the ICD implantation for prophylaxis. Results After a median follow-up of （22.3 ± 13. 4） months, all patients were alive. One patient was suspected with febrile syndrome due to endocarditis on the auricular face of the lead of defibrillator 18 months after 1CD implantation and disappearance of vegetation was found after receiving one-month antibiotic treatment. Nine appropriate ICD interventions took place in 3 individuals with documented spontaneous ventricular arrhythmias. Multivariable analysis suggested that occurrence of appropriate interventions was related to the spontaneous ventricular arrhythmias （ P 〈 0. 0001 ）. Eleven inappropriate ICD interventions occurred in 3 patients for atrial fibrillation or atrial flutter with rapid ventricular rate. Multivariable analysis suggested that occurrence of inappropriate interventions was related to documented spontaneous supraventricular arrhythmias （P 〈 O. 0062 ）. All appropriate interventions and inappropriate interventions occurred within six months after ICD implantation. Conclusion Appropriate interventions may associate to spontaneous ventricular arrhythmias before 1CD implantation in patients with Brugada syndrome. Patients may suffer from inappropriate ICD intervention for supraventricular arrhythmias with rapid ventricular rate when they had a history of supraventricular arrhythmias.
