What does decrease in stroke volume implies?

What does decrease in stroke volume implies?

Weak heart: Decrease in stroke volume means the heart muscle is not contracting as strongly as it should. This may result in thrombus formation and brain stroke. Check with your md on this. ...Read more

An increased stroke volume would be a consequence of what?

Stroke volume: Stroke volume is the amount of blood pumped by the heart with each beat. This could be due to increased fluid volume in the body, fever and tachycardia in the face of normal blood volume, increased catecholamine state is another. There are other possibilities also. ...Read more

Why does a higher stroke volume reduce angina ?

Stroke volume: Stroke volume is the amount of blood ejected from the heart with each beat. A higher stroke volume implies increased cardiac contractility which means more oxygen demands by the heart muscle. In the presence of significant coronary artery disease, this increased contractility will increase, not reduce, angina. ...Read more

Why must stroke volume for both ventricles be the same?

Why must stroke volume for both ventricles be the same?

Stroke volume (SV): The left and right sided chambers of your heart are like 2 pumps. All the volume from the first pump should be equal to what's used in the second. Too little blood=anemia, Smaller SV in one pump suggests a leak (shunt) versus bad pump (heart failure). Your body is always fighting to maintain a balance. When balance is disrupted, that is often when you feel ill. ...Read more

Why must the stroke volume for each ventricle be the same?

Why must the stroke volume for each ventricle be the same?

Circuits in series: Since the left (systemic) and right (pulmonary) circuits are in series with each other, the blood that each ventricle pumps is the blood that has just come from the other ventricle! now, this is not always true in congenital heart disease where there are connections (shunts) between the two systems. ...Read more

How are stroke volume and cardiac output distinguished from each other?

How are stroke volume and cardiac output distinguished from each other?

Cardiac output: Stroke volume times heart rate equals cardiac output. Stroke volume relates to myocardial contractility, vascular resistance, vascular volume, anemia and metabolic state. There are subcomponents to all of these. ...Read more

How much would 40 minutes a day exercise increase the overall stroke volume of the heart in 3 months in a male 22?

Stroke volume: 3 months of aerobic exercise as described might make no change in stroke volume, if it did it would be subtle. It takes a long time to begin to see benefits from exercise and usually at least 6 weeks to see anything. Stroke volume would likely take 6mo to a year to measure something real. ...Read more

I have an EF of 48%, and a stroke volume of 46.9 mL, and my cardiologist isn't concerned. I'm 25 years old. I'm super worried, what should I do?

I have an EF of 48%, and a stroke volume of 46.9 mL, and my cardiologist isn't concerned. I'm 25 years old. I'm super worried, what should I do?

Re-test: For an otherwise healthy young person an EF of 48% is not Normal. Not sure by what imaging modality that was quantified, but it ought to be re-done, preferably without radiation exposure. See another cardiologist, get a second opinion, perhaps at an academic center. ...Read more

In what way damage to the conduction system of the heart impact stroke volume?

Lower stroke volume: If part of your heart are not properly innervated, the muscle will not contract as needed and the stroke volume may diminish. Uneven contraction may lead to thrombus formation and potentially stroke, check with your cardiologist. ...Read more
