[Electrocardiography in the diagnosis of genetic heart diseases--the Brugada syndrome].

Electrocardiography celebrates its 100th anniversary but is still a useful and widely used examination method in cardiac diseases. Its importance can be demonstrated on its part in the diagnosis of a relatively newly described disease presented in this paper. It is a genetically conditioned anomaly of sodium channels of the cell membrane, called Brugada syndrome. The latter has a typical electrocardiographic tracing--elevations of the ST segment in leads V1-V3 along with a finding reminding of a right bundle branch block, absence of structural cardiac disease and an increased incidence of serious ventricular arrhythmias and sudden arrhythmic death.
