Stroke Volume

Cardiac stroke volume (SV) is the volume of blood that is ejected by the heart into the arterial system during systole. This is an important indicator of the functioning of the cardiovascular system, which may indicate the presence of health problems and requires monitoring.

SVR is measured in milliliters (ml) and depends on many factors, including age, gender, weight, physical activity and health status. In healthy people, the SV is about 70 ml, but can vary depending on various factors.

Measurement of SVR can be carried out using echocardiography, which allows you to estimate the size of the heart chambers and the volume of blood pumped into the arterial system. In addition, the UOS analysis can be included in a general blood test, which reflects the health of the cardiovascular system.

A decrease in SVR may indicate the presence of heart failure, coronary heart disease, hypertension and other diseases. An increase in heart rate may indicate an increased level of heart activity or other health problems.

Controlling your blood pressure is an important step to maintaining cardiovascular health and preventing the development of serious diseases. Regularly measuring SOS and analyzing the results can help identify problems early and take action to correct them.

Stroke (systolic) blood volume is the amount of blood that is ejected from the left ventricle into the aorta in one contraction (systole). Normal stroke volume is 60-120 ml for men and 40-90 ml for women, depending on age, body weight, physical activity and other factors. Although in a healthy person the heart contractions are not rhythmic, and the interval between them - the R-R interval - is highly variable, the stroke volume remains constant.

Reasons for changes in stroke volume: * vascular stenosis * cardiomyopathy * increase in the LV cavity * decrease in cardiac output * decrease in cardiac index * increase in pressure in the vessels (due to an increase in blood volume)
