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 moreSee 1 more doctor answer
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
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
Which value of cardiac output is considered high? My stroke volume 90ml, by 75 bpm, that means cardiac out:6, 7l/min;cardiac index would be 3, 5l/min*m2.Tx
Cardiac Output: Numbers such as you list can be normal especially in a smoker. Numbers alone without clinical correlation don't necessarily mean a lot. You should discuss these data with the physician (s) who know you and your specifics. ...Read more
Is my cardiac output too high? Results from echo:stroke volume 100ml, by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.
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
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
What are the signs and symptoms of left sided heart failure associated with decreased cardiac output?
Swelling: The left side of the heart pumps blood throughout your body. When it fails, it decreases blood flow to organs. This can cause kidney injury, liver injury, fatigue, shortness of breath with little exertion, swelling of the feet and legs, fluid build-up in the lungs, and difficulty sleeping flat due to shortness of breath. Medications and diet are important for this disease! ...Read more
What are the signs and symptoms of left sided heart failure due associated with decreased cardiac output?
Congestion: Breathlessness, especially with exertion. Easy fatigability. Impaired exercise capacity. These are early signs. Without treatment, one becomes short of breath resting, especially when lying down (orthopnea) and at night (paroxysmal nocturnal dyspnea). Eventually the right heart also fails leading to swelling (edema), abdominal fluid (ascites and effusions), and cachexia (wasting). ...Read more
Multiple things: Cardiac output is the product of heart rate in stroke volume. Thus, an increase in heart rate results in an increase in cardiac output. Stroke volume can be affected by changes in preload, afterload, and contractility (strength of contraction). Preload is "priming the pump". Afterload is the resistance to ejection during systole (contraction). ...Read moreSee 1 more doctor answer
Related but not the: Same. Co is a mathematical calculation of the amount of blood pump by the left ventricle of your heart in one minute (stroke volume x hr). The ejection fraction is a measurement of the percentage of blood leaving your left ventricle every time contract. Can be measure by 2d echocardiogram, cardiac catheterization, nuclear scan, mri. Hope it help. ...Read moreSee 1 more doctor answer
Cardiac output: Basically an increase in demand for oxygen by the body. This may be physiological (exercise) or pathological (sepsis - infection - fever) or increased metabolism (hyper active thyroid gland - hyperthyroidism) or abnormal conducts (shunting of blood). ...Read moreSee 1 more doctor answer
