Evaluation of Syncope It results from arrhythmias, mechanical abnormalities, or structural abnormalities, and is generally seen in older adults. Cardiac causes of syncope often are unprovoked and are more likely to present in the emergency department. Sudden death in young adults with syncope is often the result of arrhythmias. Orthostatic hypotension can be caused by autonomic dysfunction, medications, or volume depletion resulting in syncope. It is rare in patients younger than 40 years, and is commonly seen in older patients with comorbid conditions.1,6.

Understanding Fainting -- the Basics Fainting may have a variety of causes. A simple episode, also called a vasovagal attack or neurally-mediated syncope, is the most common type of fainting spell. It is most common in children and young adults. A vasovagal attack happens because blood pressure drops, reducing circulation to the brain and causing loss of consciousness. If the syncope is prolonged, it can trigger a seizure. You may suffer from a simple fainting spell due to anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs.

- Vasovagal syncope is a common cause of fainting. The vagus nerve is overstimulated and causes the body's blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward to the brain against gravity. Without blood flow, the brain turns off.
