What is an expected stroke volume at rest, approximately?

The expected stroke volume at rest is approximately 70 ml, which is considered a standard measurement for a healthy adult at rest. Stroke volume refers to the amount of blood pumped by the left ventricle of the heart in one contraction. A stroke volume of around 70 ml indicates that the heart is functioning efficiently when the body is at rest, ensuring that organs and tissues receive adequate blood flow and oxygen without the increased demand that physical activity entails.

This value can vary based on various factors, including individual fitness levels, body size, and overall cardiovascular health, but 70 ml serves as a widely accepted average for a resting stroke volume in a well-conditioned individual. In contrast, values significantly lower than this might suggest an unhealthy or compromised cardiovascular system, whereas much higher values could indicate either exceptional athletic conditioning or underlying medical conditions. Understanding normal anatomical and physiological parameters like stroke volume is essential for health professionals in assessing cardiovascular health and overall fitness.
