Rate-Pressure Product (Double Product)
Rate-pressure product = heart rate (bpm) x systolic BP (mmHg); a surrogate for myocardial oxygen demand.

Example
- Heart rate
- 80 bpm
- Systolic BP
- 140 mmHg
Result: Rate-pressure product 11200 — myocardial oxygen demand surrogate.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- HR x SBP
- Myocardial oxygen-demand surrogate. Resting typically < 10000; peak-exercise > 20000 reflects good reserve, < 16000 impaired. A physiologic value, not a diagnosis.
What you enter
- Heart rate
- Systolic BP
