    Syncope, commonly known as fainting, refers to a sudden loss of consciousness, followed by a rapid and complete recovery. If you have symptoms of dizziness or lightheadedness, without loss of consciousness, this is often called presyncope, but these symptoms may be due to conditions that are unrelated to syncope.

    Frequency  Syncope is surprisingly common in the population, but individual patients, if they have syncope, rarely experience more than one episode in a lifetime Approximately one-third of people have a syncopal episode at some point in their life. In most cases, syncope is not a sign of a life-threatening problem, although some people with syncope...

    Risks  A person who suddenly and unexpectedly loses consciousness can be injured. Up to 35 percent of people who have syncope injure themselves; elderly people are more likely to be injured during a syncopal attack. (See 'Safety issues' below.)

    To remain conscious, a supply of oxygen-rich blood must be pumped to the brain without interruption. If the brain is deprived of this blood supply, even for a brief period, loss of consciousness (passing out) will occur.

    A number of medical conditions can cause syncope. Some of the most common are listed here. Sometimes, sinus bradycardia occurs because of an abnormality in the sinus node itself. This is called sick sinus syndrome. In other cases, the slowed firing of the sinus node is due to medications. In still others, problems with the nerves that lead to the h...

    Vasovagal syncope  One of the most common types of syncope is called vasovagal syncope or neurocardiogenic syncope. A variety of conditions can trigger vasovagal syncope, including physical or psychological stress, dehydration, bleeding, or pain. The heart rate slows dramatically and the blood vessels in the body expand, causing blood to pool in th...

    In most cases of vasovagal syncope, you have some warning that you are near fainting. These signs include dizziness, feeling hot or cold, nausea, pale skin, \\"tunnel-like\\" vision, and profuse sweating. After the episode, symptoms may continue because of continued low blood pressure. Some people feel extremely tired.

    Sinus bradycardia  Bradycardia means a slow heart rate. In sinus bradycardia, the heart rate is slower than normal. A dramatically slowed heart rate can decrease the blood supply to the brain by reducing the amount of blood that the heart can pump per minute. Orthostatic hypotension  Hypotension means low blood pressure. Orthostatic hypotension ref...

    Heart block  Sometimes, part of the conduction system between the sinus node and the rest of the heart becomes disrupted due to heart disease. Most often, this occurs in the middle of the heart where a special set of fibers conduct the electrical impulse to the pumping chambers (the ventricles), preventing the normal flow of electrical impulses. If...

    Most people with syncope due to VT have underlying heart disease, most commonly coronary heart disease. Treatment of people with syncope caused by VT usually includes an implantable cardioverter-defibrillator. (See 'Implantable cardioverter-defibrillator' below.)

    SYNCOPE DIAGNOSIS There are three main ways to identify the causes of syncope: the medical history, the physical examination, and cardiac testing. A medical history and physical examination are recommended for anyone who has had syncope. Some people will also require cardiac testing. Medical history  Gathering as much information as possible about ...

    As an example, vasovagal syncope is suspected in a person who has warning signs of nausea or sweating. In contrast, a sudden loss of consciousness with no warning is more likely to be due to a heart rhythm problem. A person who has syncope during exertion is more likely to have an obstruction to blood flow (aortic stenosis or hypertrophic cardiomyo...

    Echocardiogram  An echocardiogram is useful for identifying underlying structural heart disease such as hypertrophic cardiomyopathy or significant aortic stenosis. These findings alone do not conclusively establish the specific cause for syncope.

    An echocardiogram uses ultrasound (sound waves) to obtain detailed pictures of your heart as it beats. A technician presses a transducer (wand) against your chest and abdomen. The transducer is attached to a recording device and monitor. You are awake during the procedure. An echocardiogram does not use radiation. Upright tilt table test  This test...

    Most people undergo EPS in a hospital setting. You will be given a sedative before the procedure but may be awake during testing. The physician uses a local anesthetic to numb a small area over a blood vessel, usually in the groin, and then threads small wires through the blood vessels into the heart using x-ray (fluoroscopic) guidance. Once in the...

    Exercise testing  In some people, especially those with a history of syncope during exertion, an exercise test is useful. Your blood pressure, heart rate, and rhythm are monitored while exercising on a treadmill or bicycle.

  3. Mar 12, 2020 · Syncope or fainting is a temporary loss of consciousness. It is often related to insufficient blood flow to the brain. It's also called fainting or "passing out." It most often occurs when blood pressure is too low (hypotension) and the heart doesn't pump enough oxygen to the brain.
