> The rate pressure product calculator multiplies heart rate by systolic blood pressure to estimate how hard the heart muscle is working and how much oxygen it needs – useful during exercise testing and cardiac rehabilitation.

## Inputs

- Heart rate (bpm)
- Systolic blood pressure (mmHg)

## Results

- Rate pressure product

## Formula

```
RPP = heart rate × systolic blood pressure
```

## Explanation

Myocardial oxygen demand rises with both heart rate and pressure, so their product is a simple index of cardiac workload. Resting values are usually 6,000–12,000; a peak value above 25,000 during exercise is a good sign of cardiac fitness.

### How to use the Rate Pressure Product Calculator

- **Heart rate**
- **Systolic blood pressure**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter heart rate and systolic blood pressure taken at the same moment.

### Inputs explained

### Example values

How the main result changes when **Heart rate** changes and everything else stays at the example values above:

## Worked example

Inputs — Heart rate: 75 bpm; Systolic blood pressure: 120 mmHg.

Results — **Rate pressure product = 9,000 mmHg·bpm**.

## Key terms

- **RPP**: Rate pressure product, also called double product.

## FAQ

**What is a normal RPP?**
About 6,000–12,000 at rest.

**Why does angina occur at a certain RPP?**
Many people with coronary disease get angina at a consistent workload, so RPP helps set exercise limits.

**Does RPP measure fitness?**
A high peak RPP during a stress test reflects good cardiac capacity.
