What is the approximate cardiac output of a person with a heart rate of 70 beats min and a stroke volume of 75 ml?

What is the approximate cardiac output of a person with a heart rate of 70 beats min and a stroke volume of 75 ml?

The stroke volume (SV) is the volume of blood, in milliliters (mL), pumped out of the heart with each beat. Increasing either heart rate or stroke volume increases cardiac output. Cardiac Output = 70 (beats/min) X 70 (mL/beat) = 4,900 mL/minute or 4.9 L/min.

What would be the heart rate of a person if the cardiac output is 5 Litre?

What would be the heart rate of a person if the cardiac output is 5L, blood volume in the ventricles at the end of diastole is 100 ml and at the end of ventricular systole is 50 ml? A) 50 beats per minute. B) 75 beats per minute.

What would be the cardiac output of a person having 72 heart beats per minute?

Thus, 72 x 50 = 3600 mL is a person’s cardiac output of 72 heartbeats per minute and 50 mL of stroke volume.

What is called heart of heart?

SA node is located in right atrial wall below the opening of the superior vena cava. It initiates each cardiac cycle. This is also known as pacemaker or “heart of heart” because it functions as originator of cardiac impulse AV node is also called pace setter.

What are the factors that determine cardiac output?

Although most clinicians should/will be able to recite the four determinants of cardiac output – heart rate, contractility, preload, and afterload – understanding of the applicability and practical relevance of each of these four components is all too often less well ingrained.

What will be the cardiac output of a person whose stroke volume is normal and heart rate is 80 per minutes?

Cardiac output is calculated by multiplying the stroke volume by the heart rate. Stroke volume is determined by preload, contractility, and afterload. The normal range for cardiac output is about 4 to 8 L/min, but it can vary depending on the body’s metabolic needs.

What are the four factors that influence cardiac output?
