Systemic vascular resistance is 1700 dynes cm⁻⁵.Which of the following is consistent with this value?
A) Elevated left-ventricular afterload
B) Elevated right-ventricular afterload
C) Decreased left-ventricular preload
D) Decreased right-ventricular preload

Question

Quizplus · Accepted Answer

The normal range for systemic vascular resistance is 900 to 1500 dynes cm⁻⁵.Preload is defined as the filling pressure of the ventricles at the end of ventricular diastole.Afterload represents the resistance the ventricles must overcome to eject blood.Therefore,an elevated systemic vascular resistance would cause an elevated left-ventricular afterload.
