Can you tell me what occurs to heart rate, stroke volume and cardiac output during exercise?

Can you tell me what occurs to heart rate, stroke volume and cardiac output during exercise?

All increase: Exercise causes an increased demand for blood flow to provide oxygen to the muscles doing the work. This is accomplished by increase in heart rate and stoke volume. Since cardiac output is determined by heart rate and stroke volume, it also goes up. Blood pressure also typically increases with strenuous exercise. ...Read more

Not always : Depend on how severe is the pancreatitis. Mild to moderate inflammation associated with pain will increase hr and BP too. During severe attack of pancreatitis a systemic inflammatory response occur, causing a hyperdynamic response in your body. That will decrease your BP and increase your hr and increase your cardiac output. ...Read more

What is the medical explanation for low heart rate during exercise?

What is the medical explanation for low heart rate during exercise?

Several: There are several possibilities. If you're a seasoned athlete, it's due to improved stroke volume (blood ejected with each contraction) requiring a reduced heart rate to achieve a given cardiac output (the product of sv and hr). Other possibilities are: medications, vagal reactions, chronotropic incompetence, av nodal block, or sick sinus syndrome. Incidentally, typhoid fever can cause it too. ...Read more

Can you tell me in an ecg, why does the amplitude of your heart rate and pulse change when one is dehydrated?

Can you tell me in an ecg, why does the amplitude of your heart rate and pulse change when one is dehydrated?

Physiology: Cardiac output depends on stroke volume (the volume pumped in 1 beat) and heart rate. When dehydrated, your preload is reduced reducing stroke volume, so the heart speeds up to compensate in its attempt to maintain stable cardiac output. (IOW, if you can't pump more, pump faster). ...Read more

Can you tell me how the brain's response causes the increase in blood pressure required during exercise?

Can you tell me how the brain's response causes the increase in blood pressure required during exercise?

What does gait weakness mean? Also, any idea what would cause elevated epinephrine levels and heart rates that race multiple times a night and races at the slightest movement?

What does gait weakness mean? Also, any idea what would cause elevated epinephrine levels and heart rates that race multiple times a night and races at the slightest movement?

Pheochromocytoma: A pheochromocytoma is a growth in the area of the adrenal glands that causes hypertension, elevated catecholamine levels and palpitations. It is not a common condition and an endocrinologist is best qualified to evaluate for one and I recommend that you consult one in view of your symptoms. He/she will order the appropriate tests and refer you to a cardiologist if it is deemed advisable. ...Read more

What causes an increase in heart rate when exercising at high intensity? My heart rate went from 180 to 220.

Normal response: But that is too high for you -- your maximum should be no more than 180 and keep it there for about 30 minutes for a proper cardio or aerobic exercise -- and do it regularly 3 times a week -- as you get fitter, your heart rate will lower and it will take longer and higher intensity to get to your maximum heart rate -- don't overstress your heart in a hurry -- it's not a goal but a lifestyle. ...Read more

Can you tell me how the brains response causes the increase in blood pressure required during exercise?

Can you tell me how the brains response causes the increase in blood pressure required during exercise?

?: Not sure of your question. The brain modulates many bodily functions, but most of the input affecting BP comes from adrenal gland and kidney input as well as some input from baroreceptors in the carotid arteries. There are control centers that monitor and to some degree regulate this response, and can provide powerful reactionary responses for example in the case of a hemorrhagic stroke. ...Read more
