Most of the treatments for heart failure act by reducing the endogenous compensatory mechanisms. What are the compensatory mechanisms and how can they make the condition worse? How do heart failure medications have their effects? Thank you!

What is the consequence of the prolonged plateau of depolarization in ventricular myocytes? a-it causes ventricular myocytes to contract for a longer time, allowing the ventricles time to empty b-it gives additional time for the atria to contract, filling the ventricles more completely c-it causes repolarization to be delayed which slows heart rate d-it allows the ventricles a moment to rest before completing contraction
