Vasovagal syncope. Vasovagal syncope is a sudden loss of consciousness mediated by the vagus nerve. It occurs when the vagus nerve is overreactive to certain triggers, such as the sight of blood or extreme emotional distress, and causes a sudden drop in blood pressure.
But if you have had recurrent episodes, you are likely to have even more episodes unless you are effectively treated. And, as anyone with vasovagal syncope knows, these fainting episodes often come at the most inconvenient or impractical times, and can greatly disrupt your life. Fortunately, treatment is usually quite helpful. There are four general types of therapy for vasovagal syncope: education, medication, exercise and pacemakers. Of these, education is by far the most effective for the majority of people.
