Rate-Pressure Product Calculator
HR × SBP — myocardial oxygen demand as a number, used in stress testing and angina thresholds.
RPP tracks measured myocardial oxygen consumption closely — useful because angina in a given patient tends to recur at a *reproducible* double product (their 'ischaemic threshold'), whatever combination of pulse and pressure reaches it. Stress tests aim for ≥25,000 to call the workload adequate. Beta-blockers lower the RPP at any exertion level — exactly their anti-anginal mechanism.

Frequently asked questions
How does the Rate-Pressure Product Calculator work?+
RPP tracks measured myocardial oxygen consumption closely — useful because angina in a given patient tends to recur at a *reproducible* double product (their 'ischaemic threshold'), whatever combination of pulse and pressure reaches it. The calculation uses the formula: RPP = HR × SBP. Everything runs instantly in your browser as you type — your inputs are never uploaded.
Is the Rate-Pressure Product Calculator accurate, and what is it based on?+
The method is traceable to authoritative sources: Gobel FL et al., Circulation 1978 — RPP and myocardial O₂ consumption. Results are estimates — individual variation always applies, so treat the output as a well-grounded starting point.
Is the Rate-Pressure Product Calculator free and private?+
Yes. It's completely free with no sign-up, and all computation happens locally in your browser, so none of your health data ever leaves your device.
Can I use this for medical decisions?+
This is a reference aid for healthcare professionals and must be independently verified. It is not for self-diagnosis or self-medication.
What can I use the Rate-Pressure Product Calculator for?+
It's commonly used for rate pressure product, double product, myocardial oxygen demand. HR × SBP — myocardial oxygen demand as a number, used in stress testing and angina thresholds.
