When to use
Exercise testing and angina threshold assessment.
How it works
RPP = heart rate × systolic BP. Resting typically < 12,000; > 20,000 indicates high demand.
Key points
- Indexes myocardial oxygen consumption.
- Rising RPP at symptom onset marks the ischaemic threshold.
- Used during stress testing.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Heart rate | 70 bpm |
|---|---|
| Systolic BP | 120 mmHg |
