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.  aCARDIOLOGÍA911301  aCARDIOPATÍA CONGÉNICA954077  aCUIDADOS INTENSIVOS95208  aMEDICINA DE URGENCIAS GENERAL954078  aGERIATRÍA91852  aENFERMEDAD VALVULAR CARDIACA954079  aNEUROLOGÍA  aMEDICINA CLÍNICA HOSPITALARIA9537540 022717922644dMassachusetts NEJM GroupoNEJM009tThe New England Journal of Medicine wESSALUDx0028-4793  cARTICULOSe2026-08-17zSQB  c22821d22821
