Accurate diagnosis relies on careful history taking and physical examination, as well as targeted testing guided by risk stratification. Management of syncope is determined on the basis of the underlying mechanism and focuses on reducing recurrence and injury risk. In older patients, syncope may manifest as unexplained falls. Early identification of high-risk features is critical to prevent adverse cardiovascular outcomes.  aCARDIOLOGÍA  aCARDIOPATÍA CONGÉNICA  aCUIDADOS INTENSIVOS  aMEDICINA DE URGENCIAS GENERAL  aGERIATRÍA  aENFERMEDAD VALVULAR CARDIACA  aNEUROLOGÍA  aMEDICINA CLÍNICA HOSPITALARIA0 022717dMassachusetts NEJM GroupoNEJM009tThe New England Journal of Medicine wESSALUDx0028-4793
