Which measurement reflects the afterlaod of the right ventricle?
A) PVR
B) RVSWI
C) SVR
D) LVSWI

Question

Quizplus · Accepted Answer

PVR, or pulmonary vascular resistance, reflects the afterload of the right ventricle since it represents the resistance the right ventricle has to pump against to push blood through the pulmonary circulation. An increase in PVR means an increase in afterload for the right ventricle, which can lead to right heart failure. RVSWI, or right ventricular stroke work index, is a measure of myocardial contractility and doesn't directly reflect afterload. SVR, or systemic vascular resistance, reflects the afterload of the left ventricle since it represents the resistance the left ventricle has to pump against to push blood through the systemic circulation. LVSWI, or left ventricular stroke work index, is a measure of myocardial contractility and doesn't directly reflect afterload of the right ventricle.
