The Modified Valsalva Maneuver: Practical Treatment or Pointless Trick?

REBEL EM

Background: The REVERT Randomized Controlled Trial demonstrated the superiority of the modified valsalva maneuver (MVM) over the standard valsalva maneuver (VM) in re-establishing normal sinus rhythm (NSR) in patients with PSVT (Appelboam 2015). MVM exaggerates venous return to the heart and increases vagal outflow by elevating the patient’s legs.

Dietary changes may treat pulmonary hypertension

ScienceDaily

Blood vessels in the lungs aren't like the others in the body. This difference becomes clear in pulmonary hypertension, in which only the lungs' blood vessels stiffen progressively, leading to chronic lung disease, heart failure and death. The underlying reasons for this organ-specific vessel stiffening remained a mystery until researchers made a surprising discovery about these blood vessel cells in patients with pulmonary hypertension -- they're hungry.
