What is Stroke volume can be decreased by which of the following? and explain in detail?
Stroke volume is determined by preload, afterload, and contractility Increasing heart rate decreases the time for filling during diastole and may decrease preload and therefore stroke volume. Increasing preload by increasing central venous pressure will increase stroke volume. Similarly, decreasing afterload by decreasing total peripheral resistance or systemic blood pres sure will cause an increase in stroke volume, Increasing contractility will also increase stroke volume.
