Do Symptoms Predict Cardiac Arrhythmias and Mortality in Patients With Syncope?

Abstract

Symptoms, although important in assigning many noncardiac causes, are not useful in risk-stratifying patients whose cause of syncope cannot be identified by other history and physical examination. Triage decisions and management plans should be based on pre-existing cardiac disease or electrocardiographic abnormalities, which are important predictors of arrhythmic syncope and mortality.
