Rate Pressure Product (RPP) Calculator
Calculate RPP (HR × SBP), a measure of myocardial oxygen demand. Normal resting RPP is 5,000–10,000 mmHg·bpm. RPP during exercise indicates cardiac workload capacity.

Key Takeaways
- • RPP correlates with myocardial oxygen consumption
- • Used to set safe exercise intensity in cardiac rehab
- • Beta-blockers lower RPP by reducing heart rate
- • RPP >25,000 may indicate elevated ischemic risk in susceptible patients
Did You Know?
How Does RPP Work?
Formula
RPP = heart rate (bpm) × systolic blood pressure (mmHg). No unit; used as an index.
Clinical Use
Stress testing, exercise prescription, cardiac rehab. Higher RPP at same workload may indicate reduced efficiency.
Limitations
Does not include diastolic pressure. Individual ischemic thresholds vary. Use with full clinical context.

|---|---|
| <12,000 | Rest / Low |
| 12,000–16,000 | Light exercise |
| 16,000–20,000 | Moderate exercise |
| >25,000 | Vigorous / Peak |
Frequently Asked Questions
What is RPP?
Rate Pressure Product (RPP) = HR × SBP, a measure of myocardial oxygen demand. Normal resting RPP is 5,000–10,000 mmHg·bpm. RPP during exercise indicates cardiac workload capacity.
What are normal RPP values?
Resting RPP: 5,000–10,000. Light exercise: 12,000–16,000. Moderate: 16,000–20,000. Peak exercise: 20,000–40,000. Values >25,000 may indicate elevated ischemic risk in susceptible patients.
What is exercise RPP?
RPP increases with exercise as HR and SBP rise. Peak exercise RPP typically reaches 20,000–40,000. Cardiac rehab often targets 60–70% of peak RPP for safe training intensity.
What is the clinical significance?
RPP correlates with myocardial oxygen consumption (MVO₂). Used in stress testing, exercise prescription, and cardiac rehab. Higher RPP at same workload may indicate reduced cardiac efficiency.
RPP vs double product?
RPP and double product are the same: HR × SBP. The terms are interchangeable. No unit; used as an index of cardiac workload and oxygen demand.
What is the angina threshold?
RPP >30,000 can approach the double product at angina threshold in some patients with coronary disease. Beta-blockers lower RPP by reducing HR, which may delay or prevent angina.
