Electrocardiographic Findings Typical of Brugada Syndrome Unmasked by Cocaine Consumption
Brugada syndrome is characterized by the presence of right bundle branch block on electrocardiography and by ST-segment elevation in the right precordial leads (V1-V3), by the absence of structural cardiac abnormalities, and by episodes of syncope or sudden death. On occasion, diagnosis is made diff...

Summary: | Brugada syndrome is characterized by the presence of right bundle branch block on electrocardiography and by ST-segment elevation in the right precordial leads (V1-V3), by the absence of structural cardiac abnormalities, and by episodes of syncope or sudden death. On occasion, diagnosis is made difficult by temporary normalization of the ECG. The condition can be unmasked by potent sodium channel blockers, such as flecainide. Our patient presented with a Brugada syndrome-type ECG after intake of a large amount of cocaine.
El diagnóstico del síndrome de Brugada se caracteriza por la presencia en el electrocardiograma (ECG) de bloqueo de rama derecha y elevación del segmento ST en las derivaciones precordiales derechas, ausencia de enfermedad cardíaca estructural y episodios de síncope o de muerte súbita. En ocasiones, el diagnóstico se encuentra dificultado por la normalización transitoria del ECG y puede ser desenmascarado por bloqueadores de los canales de sodio, como la flecainida. Presentamos un caso en el que no fue un fármaco, sino el consumo de cocaína, lo que puso de manifiesto un patrón típico de Brugada. |
