How do positional maneuvers affect blood flow and murmurs - Answer✔✔--
standing/valsalva:
decreased cardiac filling,
decreases most murmurs
except MVP and HOCM
-squatting/ lying down:
increase cardiac volume,
increased murmurs
except MVP, HOCM
-sustained handgrip:
increases systemic resistance
decreases murmur in HOCM, AS

RV
prolongs systole and
delays pulmonary valve closure
