What is the most common age for vasovagal syncope?

The most common age of onset is 13 years. At the same time, nonclassical VVS often begins at an older age and can be associated with other aberrant disorders such as carotid sinus hypersensitivity, postprandial hypotension, or accompanied progressive orthostatic hypotension [5].

What is the tilt table test for vasovagal syncope?
