Does ICD implantation plus amiodarone prevent ventricular fibrillation in a patient with prominent J waves and ST segment elevation in inferior leads?
Prominent J waves and ST segment elevation in inferior leads may indicate high risk for ventricular fibrillation, which can be effectively managed with ICD implantation and amiodarone.
Recurrent ventricular fibrillation was observed in a 29-year-old Vietnamese man who did not exhibit structural heart disease. The patient's ECG showed prominent J (Osborn) waves and ST segment elevation in the inferior leads that were not associated with hypothermia, serum electrolyte disturbance, or myocardial ischemia. Rate-dependent change in the amplitude of J waves and ST segment elevation also were observed. An implantable cardioverter defibrillator (ICD) was implanted. Adjunctive treatment with amiodarone reduced J wave amplitude, preventing ventricular fibrillation and ICD shocks. Prominent J waves and ST segment elevation in the inferior leads may serve as an important diagnostic sign to detect high-risk individuals with a history of unexplained syncope. ICD implantation plus amiodarone is the treatment of choice.
Kalla et al. (Sat,) conducted a case report in Recurrent ventricular fibrillation with prominent J (Osborn) waves and ST segment elevation (n=1). Implantable cardioverter defibrillator (ICD) and amiodarone was evaluated on Prevention of ventricular fibrillation and ICD shocks. In a patient with recurrent ventricular fibrillation and prominent J waves, ICD implantation plus amiodarone reduced J wave amplitude and prevented ventricular fibrillation and ICD shocks.
