Syncope Definition
Vasovagal syncope is the most common kind of fainting. There are several syncope syndromes which all fall under the umbrella of vasovagal syncope.

Syncope Symptoms and Signs
Before losing consciousness, the individual frequently experiences a prodrome of symptoms such as lightheadedness, nausea, sweating, ringing in the ears, and visual disturbances. These last for at least a few seconds before consciousness is lost, which usuallyy happens when the person is sitting up or standing
