What else can I help you with?
Does a slower heart rate increase end diastolic volume stroke volume and force a contraction?
yes
What is the formula to get stroke volume?
stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
What happens to end diastolic volume when an increase in heart rate is not accompanied by an increase in contractility?
end diastolic volume is decreased
What happens to end diastolic volume when an increase in contractility is not accompanied by an increase in heart rate?
end diastolic volume is decreased
Does the mitral valve prolapse increase decrease the stroke volume?
Mitral valve prolapse may decrease the stroke volume, if it is associated with significant backflow. It decreases the effeciency of the left ventricular contraction.
What is end-diastolic vloume minus end-systolic volume equal?
stroke volume
Would stroke volume increase or decrease if your unhealthy?
Stroke volume can decrease if you are unhealthy. Health conditions such as heart failure, heart disease, or dehydration can negatively affect the heart's ability to pump blood effectively, leading to a decrease in stroke volume.
Is stroke volume inversely proportional to the after load?
Yes, stroke volume is inversely proportional to afterload. An increase in afterload, such as from increased vascular resistance, can lead to a decrease in stroke volume due to the additional pressure the heart has to work against to eject blood. Conversely, decreasing afterload can help increase stroke volume.
What decreases stroke volume?
Factors that decrease stroke volume include dehydration, blood loss, heart failure, and certain medications that negatively affect the heart's ability to contract effectively. Additionally, an increase in heart rate can also lead to a decrease in stroke volume as the heart does not have enough time to fill properly between beats.
What 3 factors determine stroke volume?
End-diastolic volume (EDV), total peripheral resistance (TPR), and contractility.
The Frank-Starling law of the heart describes the relationship between?
stroke volume, end-diastolic volume, and contraction strength
What happens to the pump rate when you increase the stroke volume?
When you increase the stroke volume, the pump rate can decrease. This is known as the Frank-Starling mechanism, where the heart adjusts its rate based on the volume of blood returning to it. The increased stroke volume leads to more efficient pumping, allowing the heart to beat at a slightly slower rate to maintain cardiac output.
