Discover your heart's efficiency with our Heart Blood Volume Calculator. Easily determine Stroke Volume and Cardiac Output, crucial metrics for assessing overall cardiovascular health and heart function. Get instant, accurate results to monitor your heart's performance.
Formula:
The primary calculation for understanding heart blood volume per beat is Stroke Volume (SV). If you also provide your Heart Rate, we can calculate your Cardiac Output (CO).
- Stroke Volume (SV) = End-Diastolic Volume (EDV) - End-Systolic Volume (ESV)
- Cardiac Output (CO) = Stroke Volume (SV) × Heart Rate (HR)
Where:
- Stroke Volume (SV): The volume of blood pumped out of the left ventricle per beat (measured in milliliters, mL).
- End-Diastolic Volume (EDV): The volume of blood in the left ventricle at the end of diastole (filling phase), before contraction (measured in milliliters, mL).
- End-Systolic Volume (ESV): The volume of blood remaining in the left ventricle at the end of systole (ejection phase), after contraction (measured in milliliters, mL).
- Heart Rate (HR): The number of times your heart beats per minute (measured in beats/min).
- Cardiac Output (CO): The total volume of blood pumped by the left ventricle per minute (measured in milliliters per minute, mL/min, or liters per minute, L/min).
