Zusammenfassung

El síncope es un episodio transitorio de pérdida de conocimiento de inicio súbito, duración breve y con recuperación completa de forma espontánea, que se produce por una reducción breve del flujo sanguíneo cerebral. La causa más frecuente de síncope es el síncope vasovagal, que afecta a pacientes jóvenes y tiene buen pronóstico. El síncope cardiogénico aumenta con la edad y, dependiendo de la cardiopatía responsable, puede asociarse a un riesgo aumentado de muerte súbita. La hipotensión ortostática es también una de las causas de síncope, afecta sobre todo a pacientes ancianos y puede ser secundario al uso de determinados fármacos o enfermedades que producen un fallo autonómico como la diabetes. El diagnóstico del síncope está basado en la historia clínica y la exploración física, y se recomienda la realización de un electrocardiograma en todos los pacientes. En el diagnóstico diferencial del síncope debe considerarse la epilepsia, determinados trastornos vasculares y la posibilidad de un origen psicógeno. El tratamiento de los pacientes con síncope depende de la causa subyacente.
