BRUGADA SYNDROME SHOWED CONSISTENT J WAVE ANDST SEGMENT ELEVATION IN 12-LEADELECTROCARDIOGRAM: TIME COURSE OF VARIATION ONJ WAVE

摘要

Recently variant type of Brugada syndrome, of which electrocardiograms showed J wave and ST segment elevation not in the right precordial leads, but in the inferior leads has been reported. Despite the absent of structural heart disease, a 25-year-old male had the attack of ventricular fibrillation (VF) at the time showing prominent J wave with ST segment elevation in all 12-leads except aVR lead that were not associated with hypothermia, serum electrolyte disturbance, or myocardial ischemia. He showed natural VF attack and VF was induced by EPS. After implantable cardioverter defibrillator (ICD) was implanted, the number of VF attack was disappeared and at same time J wave in extremity-eads also diminished. Moreover during no episode of VF all J wave in 12-leads were completely disappeared, but typical ST segment elevation in V,_3 leads of Brugada syndrome was observed and low grade of ST segment elevation in the other leads except aVR was remained. In this case the prevalence of J wave in 12-leads might indicate the warning marker of VF attack.
