The main aim of this study was to demonstrate that a protocol for managing syncope in the emergency department that is based on the early detection of heart disease enables patients to be diagnosed quickly and with few admissions, without there being a negative impact on prognosis. The study was performed prospectively in 199 consecutive patients (54% male; mean age, 67 [17] years) who presented with syncope at the emergency department of our hospital during a 17-month period. A 2 step diagnostic algorithm was developed in which patients initially underwent clinical and electro-cardiographic assessment, and thereafter were submitted to a diagnostic protocol that involved carrying out a sequence of diagnostic tests in the emergency room to avoid hospital admission. A presumptive diagnosis was established in 120 (60%) patients during the initial assessment. After completion of the diagnostic protocol, 78% of patients were given a clear diagnosis within a mean stay of 19 [15] h in the emergency department. Some 10% of patients were admitted. Three patients died during a mean follow-up period of 237 days. Implementation of a protocol for managing syncope in the emergency department that was based on screening patients according to the presence of heart disease enabled a large percentage to receive a diagnosis. Moreover, the majority of patients could be discharged rapidly from the emergency department without there being any negative impact on medium-term prognosis. El principal objetivo de este estudio es demostrar que un protocolo para el manejo del síncope en el servicio de urgencias basado en la detec-ción precoz de cardiopatía permite diagnosticar a los pa-cientes de forma rápida y con una baja proporción de in-gresos, sin que ello repercuta de forma negativa en su pronóstico. El estudio se realizó de forma prospectiva en 199 pacientes consecutivos (54% varones; media de edad, 67 ± 17 años) que acudieron por síncope al servi-cio de urgencias de nuestro hospital en un período de 17 meses. Se desarrolló un algoritmo diagnóstico en dos pa-sos en el que los pacientes eran sometidos a una primera evaluación clínica y electrocardiográfica y posteriormente a un protocolo diagnóstico basado en la realización se-cuencial de pruebas diagnósticas en el servicio de urgen-cias, con lo que se evitó su ingreso hospitalario. Tras la valoración inicial, se diagnosticó a 120 (60%) pacientes. Después de completado el protoco-lo, se obtuvo clasificación diagnóstica del 78% d
