and the correct answer goes to UNISSMED!!

the answer is neurally mediated and here's why:

Neurally mediated syncope (also called vasovagal or neurocardiogenic) is most common as a cause of syncope. Studies from the 1980s showed that approximately 24% of syncope is neurally mediated and 34% had an unknown cause. More recently, through increased use of tilt table testing, about 5066% of the cases previously classified as unknown are now thought to be neurally mediated. Medications cause approximately 3%, psychiatric disorders 2%, and arrhythmias 14%.
