There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
The crank angle would change the stroke. The stroke would change the volume.
increased contractility
Decreasing stroke volume leads to compensatory mechanisms such as increasing heart rate (pump rate) in order to maintain cardiac output. This relationship is known as the Frank-Starling mechanism, where the heart adjusts its pumping rate to accommodate changes in stroke volume.
Stroke-Volume
stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
Stroke volume refers to the volume of air that is displaced or compressed by the piston in a single stroke. Swept volume, on the other hand, refers to the total volume that is displaced by the piston over the entire displacement cycle, including the clearance volume. In summary, stroke volume is the volume displaced in one stroke, while swept volume is the total volume displaced throughout the entire cycle.
false, stroke volume decreases if the end volume decreases.
Lowers stroke volume
is the stroke volume
yes
Stroke volume is determined by three factors, altering any of them can change the stroke volume. These factors are preload, afterload, and contractility. The relationship is: SV = P*C/A What this means is that preload and contractility are directly proportional to the stroke volume and afterload is inversely proportional to stroke volume. If you increase preload (within certain limits), stroke volume will increase according to the Starling curve. Increasing contractility (many things can increase this), makes the heart pump harder and increases stroke volume. Increasing afterload decreases stroke volume. All of these can be reversed (decreasing preload and contractility = decreased stroke volume, etc). Get a good physiology book and it will explain all of this very well.
