❤️ Rate-Pressure Product
Estimate myocardial oxygen demand with the rate-pressure product.
Rate-Pressure Product
Heart rate (bpm)
Systolic BP (mmHg)
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.
