A. Cardiac arrhythmia
B. Seizure
C. Orthostatic hypotension
D. Vasovagal syncope
E. Hypoglycemia

Answer and topic summary

The answer is D. Vasovagal syncope

Vasovagal syncope is the most common cause of syncope. Syncope is essentially a lack of cerebral perfusion. Vasovagal syncope is usually triggered by something, such as an emotion or stress. It is benign. A leading hypothesis of vasovagal syncope is that it is due to increased parasympathetic signals and withdrawal of sympathetic nervous signals.
