[Brugada syndrome--a brand new case].
BACKGROUND
Brugada syndrome (BS) is a disorder characterized by syncope or sudden death associated with one of several electrocardiographic (ECG) patterns characterized by incomplete right bundle branch block and ST elevation in the anterior precordial leads. Patients with BS are prone to develop ventricular tachyarrhythmias that may lead to syncope, cardiac arrest, or sudden cardiac death.


METHODS
A 58-year-old woman is the first described case of Brugada syndrome in Serbia with intermittent typical changes in basic electrocardiography (ECG): ST segment elevation in the precordial chest leads like dome or coved--major form or type I. For the last 27 years the patient had suffered of palpitations and dizziness, without syncopal events. Her sister had died suddenly during the night in sleep. During 24-hour Holter monitoring the patient had ventricular premature beats during the night with R/T phenomenon and during the recovery phase of exercise testing had rare premature ventricular beats as the consequence of parasympatethic stimulation. Late potentials were positive. Echocardiography revealed left ventricular ejection fraction of 60%. We performed coronary angiography and epicardial coronary arteries were without significant stenosis and structural heart disease was excluded. In the bigining of the electrophysiological study ECG was normal, and after administration of Propaphenon i.v. Brugada syndrome unmasked with appearance of type I ECG pattern. A programed ventricular stimulation induced non sustained ventricular tachycardia. One-chamber implantable cardioverter defibrillator was implanted and the patient was treated with a combination od amiodarone and metoprolol per os. After one-year folow-up, there were no episodes of ventricular tachycardia and ventricular fibrillation.


CONCLUSIONS
Brugada syndrome is a myocardial disorder which prognosis and therapy are related to presence of ventricular fibrillation or ventricular tachycardia. Electrophysiologicaly induced malignant ventricular disorders class I are indication for implantation of cardioverter defibrilator, as also occurred in presented patient.
