What are signs of high cardiac output?

What are signs of high cardiac output?

Varies: Assuming a true high cardiac output syndrome, patients may feel flushed with a fast heart rate. Most are transient situations, but some illnesses and conditions may cause a sustained high output state, e.g., hyperthyroidism, anemia, arterio-venous malformations (congenital or acquired low resistance connections between arteries and veins), or disease like paget's. Requires confirmation by doctor. ...Read more

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

I'm curious what could happen when cardiac output is low and what if it's high?

I'm curious what could happen when cardiac output is low and what if it's high?

Low cardiac output: Cardiac output depends on heart rate and stoke volume. Therefore, the cardiac output increases when heart rate goes up in normal heart. However, when the heart is failing the stroke volume is lower as well as the cardiac out which is called heart failure . Sometimes, heart failure could occur when cardiac output is high due to other medical problems such as a severe anemia , hyperthyroidism, etc ...Read more

What happens to cardiac output and after load when when heart rate is low? does it increase because high heart rate causes decrease in CO

What happens to cardiac output and after load when when heart rate is low? does it increase because high heart rate causes decrease in CO

Varies.: BUT in a young healthy person, generally the heart rate is low because the heart is efficiently pumping and the cardiac output is good. Generally, (in normals), increasing the heart rate increases pumping and cardiac output. ...Read more
