Cause It may be caused by an irregular cardiac rate or rhythm or by changes of blood volume or distribution. Symptoms Syncope can occur in otherwise healthy people. The patient feels faint, dizzy, or lightheaded (presyncope), or loses consciousness (syncope). PrognosisSyncope is a dramatic event and can even be life-threatening if not treated appropriately. Generally, however, recovery is usually complete within minutes to hours. Treatment Non-cardiac syncope is treated acutely by lying down with the legs elevated. Infrequent episodes of non-cardiac syncope usually do not require treatment. More in Medical Obesity may speed ageing of the liver More: MedicalDiseases SPONSORED: So many prizes!
