What is the physiologic effect of left ventricular afterload reduction?
A) Decreased left atrial tension
B) Decreased systemic vascular resistance
C) Increased filling pressures
D) Decreased cardiac output

Question

Quizplus · Accepted Answer

Afterload is defined as the pressure the ventricle generates to overcome the resistance to ejection created by the arteries and arterioles.After a decrease in afterload,wall tension is lowered.The technical name for afterload is systemic vascular resistance (SVR).Resistance to ejection from the right side of the heart is estimated by calculating the pulmonary vascular resistance (PVR).The PVR value is normally one-sixth of the SVR.
