How Does Rest Affect Cardiac Output
Can you tell me if a man has a cardiac reserve of 400% and maximum cardiac output is 20 l/min, what is his resting cardiac output?

What happens if a man has a cardiac reserve of 400% and maximum cardiac output is 20 l/min, what is his resting cardiac output?
Great question: Sounds about normal for average individuals, but low for highly trained athletes. Resting cardiac output generally around 5 liters/min and 400% is 4 x the resting output. Not sure how you tested this, but it sounds about right for an average, healthy individual. If you are a highly trained athlete, or if you have symptoms of fatigue or shortness of breath, you may want to speak to a physician. ...Read more
Clarify:cardiac output too high at rest? Echo:stroke volume 100ml by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.Txs
High Cardiac Output: Cardiac output is calculated by multiplying stroke volume by heart rate. Since the amount of blood pumped by the heart is dependent on body surface area ie. A larger person needs more blood supply. If it is more than 6l/min in an average person, at rest , and associated with symptoms, the cause must be looked into. ...Read moreSee 1 more doctor answer
Exercise: In order to facilitate the increase in oxygen demand of the muscles during exercise, the heart rate and volume of blood per beat will go up. Cardiac output is the product of heart rate times stroke volume. Therefore cardiac output will increase with exercise. ...Read moreSee 1 more doctor answer
Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts. ...Read moreSee 1 more doctor answer
Can being a prior endurance athlete (but not currently trained) permanently affect cardiac output resulting in high numbers when all else is normal?
Athletic Heart: Interesting question! former athletes have been shown to have more left ventricular hypertrophy or thickened hearts that usually lessens with age and deconditioning. A thick heart can lead to poor heart filling by increased stiffness. A condition called diastolic dysfunction. This can lead to a type of congestive heart failure if it persists. Controlling hr and BP via meds can help. ...Read more
