Rate Pressure Product accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- RPP = Heart Rate * Systolic BP
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Heart Rate: 75 bpm
- Systolic BP: 120 mmHg
Expected outputs
- RPP: 9,000
- Workload: Normal Resting
Known limitations
- For educational use only. RPP is an indirect estimate of myocardial oxygen consumption.
Assumptions
- RPP is an indirect workload estimate rather than a direct measurement of myocardial oxygen consumption.
- The value is most useful when heart rate and systolic pressure were recorded accurately at the same time.
- Interpretation depends on exercise level, symptoms, medications, and the broader cardiovascular context.
Unit handling
- Heart Rate accepts values in bpm.
- Systolic BP accepts values in mmHg.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
