What is stroke volumes and cardiac output?
Systole refers to the contraction of muscle fibers in the myocardium, diastole refers to relaxation of the fibers in the myocardium, stroke volume is the volume of blood ejected from the heart during the cardiac cycle. Finally the cardiac cycle refers to all of the aforementioned items and is the entire cycle of the heart from systole to diastole. Mike Branch HAMILTON ISLAND EMERGENCY RESPONSE TEAM.
How fast does the return stroke lightning travel?
3700 miles per hour
Does sympathetic stimulation increase stroke volume?
parasympathatic N.S tends to decrease heart rate , giving more time for diastolic filling and thus increasing the EDV , and increasing the SV according to Frank-starlling law. but this doesn't imply an increase in the cardiac output , because i depend on the heart rate too(which was declined)
What is the most dangerous form of heat-related injury that results in a shutdown of body systems?
heart attack -cardiac arrest
What is the main action of cardiac glycosides on the myocardium?
cardiac glycosides ( Digoxin -Digitoxin ) used to treat Congestive heart Failures , by inhibting the Na-K ATPase channels on the cardiac muscles so increase the intracellular Na and Ca so increasing the inotropic Force of contraction and Eject more stroke Volume .
Cardiac output is determined by?
In reality, if you are NOT in cardiac failure, by the venous return. According to most books its the stroke volume times the rate - but stroke volume is not an independent variable.
Determined by heart rate x stroke volume?
cardiac output
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
What is the difference between stroke volume and cardiac output?
Cardiac output is the blood volume pushed out by the left ventricle per minute. Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.
What is the formula for calculating cardiac output?
CO=HRXSV, Where HR is heart rate and SV is stroke volume
What does heart rate and stroke volume determine?
cardiac output
Does the cardiac output equal heart rate multiplied by stroke volume?
Yes. CO = HR x SV CO - cardiac output HR - heart rate SV - stroke volume
Is stroke volume usually larger than cardiac output?
FALSE
Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
