Define Afterload, and what is it determined by?

Answer 2

the amount of FORCE required to eject the filled heart. It is determined by SVR (Systemic vascular resistance) and ventricular wall tension, because if you aren’t able to contract that muscle well, the force is not effective.

Question 3

Answer 3

They have systolic heart failure. This is diagnosed by an echocardiogram

Question 4

What is diastolic Heart failure?

Answer 4

impaired filling during diastole, which occurs in the absence of systolic dysfunction– LVEF >40%

Question 5

What occurs in Diastolic heart failure?

Answer 5

Myocardium is “stiff” and often hypertrophied and does not relax normally after contraction
