Question

three main factors that affect stroke volume and how each impacts cardiac output if that factor is increased?

Answer 1

The three main factors that affect stroke volume are contractility, preload and afterload.

Increase in contractility and preload increases cardiac output whereas increase in afterload decreases cardiac output.

What is stroke volume?

Stroke volume refers to the volume of blood that is pumped by the heart through each stroke.

The three factors that affect stroke volume and how it impacts cardiac output when increased is given below:

• contractility - an increase in contractility of the heart increases the cardiac output
• Preload - an increase in preload increases cardiac output
• afterload - an increase in afterload decreases cardiac output

Therefore, the three main factors that affect stroke volume are contractility, preload and afterload.
