Note:

Stroke Volume Index (SVI) provides an individualized measurement of heart efficiency by adjusting the volume of blood pumped with each heartbeat to the person’s body size. This allows for more accurate comparisons between individuals.

Understanding the Parameters:

• Stroke Volume (SV): Volume of blood pumped per heartbeat. Measured in mL/beat.
• Body Surface Area (BSA): Total surface area of the body, typically measured in square meters (m²). It's used to normalize cardiovascular values.

Use of the Calculator:

This calculator helps you estimate how much blood your heart pumps relative to your body size. It is helpful in clinical, fitness, and research settings to evaluate cardiac performance.

Result Interpretation:

• SVI < 33 mL/m²: May indicate reduced cardiac output. Further evaluation is recommended.
• SVI between 33 and 47 mL/m²: Normal range for healthy individuals.
• SVI > 47 mL/m²: Indicates high cardiac efficiency; common in trained athletes.

Conclusion:

The Stroke Volume Index is a valuable tool for assessing how well the heart functions in relation to an individual's size. It enhances diagnostic accuracy and is useful in monitoring overall cardiovascular health.
