ACEP Policy on Evaluating Patients with Syncope in the Emergency Department

摘要

(Level A recommendation) Older age, structural heart disease, or a history of coronary artery disease should be considered risk factors for adverse outcomes. Younger patients with syncope that is nonexertional, or without a history or signs of cardiovascular disease, a family history of sudden death, or comorbidities, are at low risk of adverse events. A family history of premature sudden cardiac death is a possible indication of serious congenital conduction abnormalities, such as preexcitation syndromes, long QT syndromes, or Brugada syndrome.
