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.
Stroke-Volume
stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
false, stroke volume decreases if the end volume decreases.
Lowers stroke volume
Stroke volume and swept volume are same in any reciprocating engine/compressor.
No. Stroke volume is the amount of blood that is pumped out of the heart with each heart beat.
The relationship between stroke volume and pump rate?
Stroke volume is used to measure the heart rate and arterial pressure. Most people who have had a heart attack or stroke or are at risk of having either of these issues must have their heart tested using stroke volume.
There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
The average stroke volume of the heart at rest for an adult is 70 ml.
The crank angle would change the stroke. The stroke would change the volume.
The stroke volume and the heart rate. The stroke volume is the volume of your blood and heart rate is how many beats there are per minute.
