The ejection rate of the heart is determined by dividing the stroke volume by the end-diastolic volume. The normal end-diastolic volume ranges from 65-240 ml. Normal stroke volume is 55-100 ml.
when increased blood supply is needed to meet increased tissue reqirements of oxygen and nutrients ,heart rate and stroke volume can be increased.
80 - 100 beats per miniute but if you are really fit you can get it down to 70 or 60 beats per miniute
no anywhere between 60 to 100 bpm is normal mine is the 50 range to a heart rate
An average cardiac output is 5L.min-1 for a human male and 4.5L.min-1 for a female.
72 beats per minute...but can slightly vary with age and sex and activity...
4 to 6 LPM
5L at rest.
4-6litres/min
5.6 L/min. for a male...4.9 L/min for a female
It's decreased ... unless the rate falls, which is the normal cardiac response.
cardiac output :)
Cardiac output (CO) is determined by the heart rate (HR) and the volume of blood pumped by each beat (stroke volume - SV). Mathematically, cardiac output can be represented by the equation: CO = HR x SV As such, if total cardiac output falls as a result of decreased stroke volume, the heart rate can increase to keep the total cardiac output normal, to a certain extent. Stroke volume is more complicated; it is determined by many different factors, including preload, afterload, competence of the atrioventricular valves, ventricular cavity size, and the strength of the squeeze of the cardiac muscle, amongst others. Any change in one of these factors requires a compensation in one or more of the others to maintain cardiac output.
cardiac output
10 liters
cardiac output is heart rate multiplied by stroke volume,
what compensations does the body have to do to defend cardiac output
cardiac output
Cardiac output is measured by techniques such as the Fick Pickle and Dilution methods. Other methods of measuring Cardiac output include Doppler ultrasound and Echocardiography.
its not cardiac rest, its cardiac ARREST. which is a heart attack.
Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.
