Rationale for change

bearing down increases intrathoracic pressure, sudden increase in BP, increase parasympathetic response thus decrease HR. why this maneuver is used for SVT.

a prolonged valsalva could cause an increase in HR due to decreased venous filling

Rejection reason

totally wrong, read phase 2 under anatomy and phys section https://www.ncbi.nlm.nih.gov/books/NBK537248/ - phase iv is after which does not apply here
