Q

when does a tilt test diagnose a patient with vasovagal syncope?

A

if reflex hypotension/bradycardia occurs + syncope

16
Q

what is suggestive of vasovagal syncope with the tilt test?

A

if reflex hypotension/bradycardia occurs without syncope

17
Q

what diagnostic can be used if symptoms of vasovagal syncope occur frequently?

A

holter monitor

18
Q

how can we manage acute vasovagal reactions?

A

supine position with legs raised
