What is the Frank-Starling mechanism
Give this one a try later!
Force of contraction depends on fiber length/ stretch
- a more stretched heart chamber will fill with more blood and will contract
more powerfully, pumping out a greater volume of blood
, Ejection Fraction formula

(SV/EDV) x 100
What is functional sympatholysis
Give this one a try later!
Active muscle releases factors that reduce α- adrenergic vasoconstriction
- process that reduces sympathetic vasoconstriction in active skeletal
muscle, allowing for increased blood flow to meet metabolic demand
during exercise
early ventricular contraction before SA node signal
Give this one a try later!
PVC (Premature Ventricular Contraction)
HR reduction due to changes in the inherent pacemaker rate
Give this one a try later!
