How it can be diagnosed and treated
Usually syncope is not dangerous aside from the danger of suffering injury from the fall, or if you faint while driving. The doctor will need to know what you were doing and how you were feeling when you passed out, how long you were unconscious, if you were confused afterwards, if this happened to you before, what medications you are currently taking, and any medical conditions you may have. The history often gives many important clues for the cause of syncope. The doctor will then examine you, checking your heart rate and blood pressure and listening to your heart, along with ordering blood tests, and a heart tracing (EKG) to look for possible cardiac abnormality.
