What is True about stroke volume is? and explain in detail?
Decreases by increase in hea rate REF: Ganong's 22' e p. 570-571 Stroke volume = cardiac output/hea rate (amount of blood pumped by hea per beat), hence stroke volume is indirectly propoional to hea rate, hence increases. Hea rate decreases stroke volume. After load is determined by peripheral resistance, hence nothing to do with stroke volume determination. Stroke volume depends upon end diastolic volume.
