Why does increasing heart rate increase stroke volume?
Increasing heart rate does not increase stroke volume. At first, increasing exertion increases both heart rate and stroke volume. As the heart rate increases, the time spent in diastole decreases, so there is less time for the ventricles to fill with blood. The stroke volume therefore stops increasing, and as the heart rate approaches the maximum heart rate the stroke volume may begin to decrease.
What disease that people suffer from make it twice as likely to have a stroke or heart attack?
the answer is high cholesterol because high cholesterol lowers your blood sugars which your brain and heart need, increasing the risk of heart attack or stroke.
How does 4-strokes engine work?
1st stroke, intake. 2nd stroke, compression. 3rd stroke, power. 4th stroke, exhaust. The 4 stroke cycle take 2 full revolutions of the crankshaft.
Why is a ct scan after a stroke done with out contrast?
A CT scan immediately after a stroke is usually looking to see if the stroke caused any bleeding. ( a hemorrhagic stroke ) If the dye were given it might hide any trace of blood. There are protocols in place as to how to treat a stroke and if bleeding is seen it changes what is done to help the patient recover from the stroke.
How can you tell if a motor is four stroke its on a kawasaki bayou 220 or do I mix gas and oilto a certain ratio which is?
Does it have valves (4 stroke) 2 stroke has ports Do you have to mix gas/oil (2 stroke)
Did Robert Frost Survive after dying of a stroke?
If he died , he could not survive.
Is There A Such Thing As A 350 Stroker Motor?
Yes, kits are available allowing you to "stroke" a 350 engine. Doing so increases the piston stroke by increasing the crankshaft "throw".
What research has been done on calcium and stroke?
A 1999 study reported that researchers have found that increasing the amount of daily calcium consumed by women may reduce their risk of stroke.
Why does increasing heart rate increase stroke volume?
Increasing heart rate does not increase stroke volume. At first, increasing exertion increases both heart rate and stroke volume.

The stroke volume therefore stops increasing, and as the heart rate approaches the maximum heart rate the stroke volume may begin to decrease.
How can stroke volume can be altered?
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.
What do hamsters do when they are in love?
When you stroke it on its hide area the female will stay very still
What is the difference between two stroke oil and four stroke oil?
Two-stroke oil burns with smaller residual ash, minimizing wear and tear inside combustion chamber and internal parts. Viscosity in two-stroke oil is reduced, increasing oil penetration to guard against higher operating temperatures and RPMs.
What disease that people suffer from make it twice as likely to have a stroke or heart attack?
the answer is high cholesterol because high cholesterol lowers your blood sugars which your brain and heart need, increasing the risk of heart attack or stroke.
Can you wake up from a stroke?
Most people survive strokes (unless they are massive ones, involving a large portion of the brain).
How long can nerve cells survive without new blood supply?
Only a few minutes, that is why stroke causes serious damage.
What hormone increases heart rate and force of contraction?
Cardiac output is defined by the equation HR (heart rate) x SV (stroke volume). Anything that increases either of these will increase the cardiac output. Increasing heart rate: exercise, anxiety, caffeine, amphetamines, cocaine, other medications Increasing stroke volume: certain medications (digoxin, etc), lower heart rates
Your dad had a stroke a month ago will he die?
AnswerIt depends on the severity of the stroke. Many people survive strokes and can be completely or partially rehabilitated with speech, walking, etc. His physician will be the best person to talk to about his prognosis (the probable outcome).
