# Rate Pressure Product Calculator

Determines myocardial workload by multiplying heart rate by systolic blood pressure.

Rate Pressure Product (RPP), also known as cardiovascular product, determines myocardial workload and is a parameter used by cardiac specialists and exercise physiologists.

RPP measures the stress put on the cardiac muscle by accounting for the number of times it needs to beat per minute (Heart Rate) and the arterial blood pressure that it is pumping against (Systolic Blood Pressure):

`Rate Pressure Product (RPP) = Heart Rate (HR) x Systolic Blood Pressure (SBP)`

The reference range for RPP is correlated with hemodynamic response:

 Rate Pressure Product Hemodynamic Response > 30,000 High 25,000 – 29,999 High intermediate 20,000 – 24,999 Intermediate 15,000 – 19,999 Low intermediate < 14,999 Low

Any total value of RPP greater than 10,000 indicates a degree of risk for heart disease.

## Rate Pressure Product Explained

Rate Pressure Product (RPP), also known as cardiovascular product, determines myocardial workload and is a parameter used by cardiac specialists and exercise physiologists.

RPP measures the stress put on the cardiac muscle by accounting for the number of times it needs to beat per minute (Heart Rate) and the arterial blood pressure that it is pumping against (Systolic Blood Pressure):

`Rate Pressure Product (RPP) = Heart Rate (HR) x Systolic Blood Pressure (SBP)`

The reference range for RPP is correlated with hemodynamic response:

 Rate Pressure Product Hemodynamic Response > 30,000 High 25,000 – 29,999 High intermediate 20,000 – 24,999 Intermediate 15,000 – 19,999 Low intermediate < 14,999 Low

Any total value of RPP greater than 10,000 indicates a degree of risk for heart disease. The fittest individuals have resting RPP level around 5,000.

RPP is indicative of the oxygen demand of the heart. In a healthy person the oxygen demands of the heart place less contributing stress in a workout, whereas in an individual with a degree of cardiac problems, there is an elevated stress from the oxygen cardiac demand and the fatigue of respiratory muscles attempting to satisfy this demand, explaining getting out of breath with slight exertion.
