[Brugada syndrome].
The Brugada syndrome is a clinical-electrocardiographic diagnosis characterised by syncopal or sudden death episodes in patients with a structurally normal heart with a characteristic electrocardiographic pattern consisting of ST segment elevation in the precordial leads V1 to V3 and a morphology of the QRS complex resembling a right bundle branch block. In many patients with the Brugada syndrome, the electrocardiographic manifestations transiently normalize; leading to underdiagnosis of the syndrome. The administration of sodium channel blockers such as ajmaline, flecainide or procainamide accentuate the ST segment elevation and can be used to unmask concealed and intermittent forms of the disease. The incidence of sudden death in this syndrome is very high and can only be prevented by implanting a cardioverter-defibrillator. Because of high incidence of familial occurrence, the extension of the testing to family members is important.
