Vasovagal syncope is the most common type of fainting, and is most common among young women. It can be triggered by several factors, including alcohol, anxiety, fatigue, hunger and prolonged standing. The heart rate and blood pressure decrease, leaving inadequate blood circulation and reduced oxygen to the brain. It can be a reoccurring condition.

Before losing consciousness, victims usually start to feel nauseous and have difficulty hearing. They have difficulty speaking, experience exhaustion, have blurry vision and feel a tightness in the throat. Symptoms can last from several seconds to a few minutes. Once a victim regains consciousness, he or she may appear flushed, and/or feel lethargic. The heart rate may be quite fast, but it usually returns to normal.


the condition

Because there can be other causes of fainting, a thorough history and physical examination must be taken. If fainting is recurrent, a table test is usually performed.

Patients lie on a table that is tilted upright so blood pressure and heart rate changes can be safely observed and monitored.


means prevention

The primary treatment is lifestyle changes. Namely, patients should avoid situations that have caused vasovagal syncope in the past. An increase in the consumption of salt and fluids can also help by increasing blood volume.

Beta-blockers can be prescribed, and if repeated episodes cause the heart to stop for a period of time, a pacemaker may be needed.
