Are beta-blockers effective for syncope?
14 doctors weighed in across 5 answers
Found rarely to be.: Syncope: a faint or passing out. There are many causes but i'll refer to the most common type: vasovagal. A variety of triggers (soldier standing too long in hot sun, med stud seeing too many mangled bodies at a train wreck) causes a surge of the parasympathetic nervous system (vagus nn), causing vessels to dilate, BP drop, pulse slow that can lead to syncope. B-blockers no longer found effective.

No good data: A randomized trial showed that there is no statistically significant benefit to beta blockers in the treatment of syncope. That said, many cardiologists still use beta blocker to treat patients.
