Ventricular contractility can be estimated by which of the following?
a. Systemic vascular resistance
b. Ejection fraction
c. Pulmonary vascular resistance
d. Left ventricular stroke work
ANS: B
The ejection fraction is a derived variable that provides an estimate of ventricular contractility. The systemic vascular resistance is an indicator of left ventricular afterload. Pulmonary vascular resistance indicates right ventricular afterload. Left ventricular stroke work reflects the pressure generated by the heart during a ventricular contraction.
