Stroke Volume Calculator
Calculating stroke volume by hand is crucial for understanding your cardiovascular health. It’s the amount of blood pumped by the heart in one contraction.
- Enter your heart rate in beats per minute (bpm).
- Enter your stroke volume in milliliters (ml).
- Click ‘Calculate’.
Stroke volume (SV) is calculated as:
SV = CO / HR
where CO is cardiac output and HR is heart rate.
| Case | Heart Rate (bpm) | Stroke Volume (ml) | Cardiac Output (L/min) |
|---|---|---|---|
| 1 | 70 | 70 | 4.9 |
| 2 | 85 | 65 | 5.525 |
| 3 | 95 | 75 | 7.125 |
| Age | Average Stroke Volume (ml) |
|---|---|
| 20-30 | 70 |
| 30-40 | 65 |
| 40-50 | 60 |
- Regular exercise can increase your stroke volume.
- High blood pressure can decrease stroke volume.
What is stroke volume?
Stroke volume is the amount of blood pumped by the heart in one contraction.
How does heart rate affect stroke volume?
Heart rate and stroke volume are inversely related. As heart rate increases, stroke volume decreases.
