ANATOMY

Detailed explanation-1: -Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the end-diastolic volume. Multiplying the stroke volume by the heart rate yields the cardiac output, typically reported in liters per minute.

Detailed explanation-2: -The definition of stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.

Detailed explanation-3: -Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70 ml. Now to get cardiac output we have to multiply stroke volume with the normal heart rate of 72 beats/min and we get 5, 040 ml/min. This means that in one minute, a normal heart pumps about 5 litres of blood.

Detailed explanation-4: -It pumps oxygen-rich blood up into the body’s main artery, called the aorta. The blood then goes to the rest of the body. According to the American Heart Association: A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal.

Detailed explanation-5: -LVSV is the volume of blood ejected from the left ventricle (LV) during one heart contraction. LVSV may be quantified, either manually or automatically, using software, and is derived from a series of parallel short axis slices or from one or more long axis slices (using geometric assumptions).
