WebThe stretch of the heart caused by the preload determines the stroke volume. This becomes the Frank–Starling Law of the Heart. The plot of cardiac output against right atrial pressure is considered to be the cardiac function curve. The effect of afterload and preload on the PV loop is considered. WebThis results in an increase in cardiac output (CO), as the heart is able to pump out more blood per beat. Parasympathetic stimulation, on the other hand, has the opposite effect and can decrease SV, CO and ESV. The formula for cardiac output (CO) is: CO = SV x HR (heart rate) Where SV is stroke volume and HR is heart rate.

WebThe afterload increases with the increase in the pulmonary and aortic pressure. Factors … WebApr 28, 2024 · Afterload is increased due to an increase in systemic vascular resistance and aortic pressure increase. An increase in the afterload leads to a decrease in the heart's stroke volume and an increase in the end-systolic volume. This also indirectly affects the heart's cardiac output due to a reduction in the stroke volume of the heart.
