What is normal RPP in stress test?
The aim during exercise stress testing is to achieve a rate pressure product of at least 25000, which indicates that the workload has been sufficient. Rate pressure product (RPP). Under normal circumstances, the coronary blood flow adapts to myocardial oxygen demand.
Why does RPP increase during exercise?
HR, SBP and RPP increases with the increase workload on the heart to provide the adequate blood supply to the active myocardium during exercise.
How is RPP measured?
RPP was calculated by multiplying heart rate by systolic blood pressure throughout the test and maximum RPP (MRPP) was identified. HRR was adjusted for age as a percentage using the formula: (maximum heart rate-resting heart rate/APMHR-resting heart rate) ×100 [7].
How is RPP exercise calculated?
Rate-pressure product (RPP), which can be used to estimate the increased metabolic demand that exercise places on the heart, is calculated by multiplying the HR and the SBP.

What is RPP physiology?
Rate pressure product (RPP) is a major determinant of cardiac oxygen consumption. It is an important indicator of ventricular function. RPP varies with exercise.
What is an abnormal Duke treadmill score?
Duke Treadmill Score The score typically ranges from −25 to +15. These values correspond to low-risk (with a score of ≥+5), moderate-risk (with scores ranging from −10 to +4), and high-risk (with a score of ≤−11) categories.
What is a good Mets score for a stress test?
Exercise capacity is based on metabolic equivalents (MET) achieved, (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5–8 METS is fair, 9–11 METS is good, and 12 METS or more is excellent.
What is RPP heart?
Introduction: The product of heart rate and systolic blood pressure, termed as rate-pressure product (RPP), is a very reliable indicator of myocardial oxygen demand and is widely used clinically. There have been previous attempts to describe the relationship between RPP and the onset of pain in angina pectoris.
What does RPP stand for in exercise?
Rate-pressure product (RPP), which can be used to estimate the increased metabolic demand that exercise places on the heart, is calculated by multiplying the HR and the SBP.
What is a normal double product?
Double product closely reflects the directly measured myocardial oxygen uptake and coronary blood flow over a range of exercise intensity. Standard values of DP vary from 6000 at rest (HR, 50b/min; SBP, 120 mmHg) to 40000 during very intense exercise (HR, 200 b/min; SBP, 200 mmHg) (Katch, McArdle, & Katch, 2010).
How is RPP measured?
RPP was calculated by multiplying heart rate by systolic blood pressure throughout the test and maximum RPP (MRPP) was identified. HRR was adjusted for age as a percentage using the formula: (maximum heart rate-resting heart rate/APMHR-resting heart rate) ×100 [7].
How does RPP measure heart rate?
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)
What does RPP mean in exercise?
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.
What is the RPP in cardiology?
Rate Pressure Product (RPP), also known as cardiovascular product, determines myocardial workload and is a parameter used by cardiac specialists and exercise physiologists.
When is the rate pressure product measured?
The rate pressure product is usually measured at rest and then with the patient engaged in various stages of exercise. For each determination, both the heart rate and systolic pressure will be registered.
How does the rate pressure product calculator work?
This health tool computes the RPP based on the maximum heart rate and the maximum systolic blood pressure. The rate pressure product offers information on the myocardial workload during the physiology of exercise.
What does RPP mean in cardiac?
The RPP shows how much stress is put on the cardiac muscle given the number of beats per minute and the arterial (systolic) pressure it needs to pump against.
What is the reference point for RPP?
In some cases, clinicians will use the target heart rate , also known as the exercise target zone as the reference point for calculating a safe RPP. Some consider the RPP as an index for myocardial oxygen consumption, similar to the MVO2.

What is the RPP of a heart?
Rate Pressure Product (RPP) is a valuable marker of cardiac function.It is the product of heart rate (HR) and systolic blood pressure (SBP) (HR x SBP/1000). RPP up to 12 at rest and up to 22 in stressed conditions is considered as normal. This study deals with RPP evaluation in60 young normal subjects of 18 to 22 years old (30 males and 30 females).HR and SBP were recorded before and after 5 min of mental stress (mental arithmetic) and physical stress (cycling) from which RPP was calculated.RPP increased significantly after mental stress in both the genders (males (M) p< 0.0001 and females (F) p< 0.0005). But there was no gender difference in the level of increase. After physical stress also RPP increased in males significantly (p<0.0004)and in females non-significantly (p<0.143).Determination of RPP is the best non-invasive and time sparing method of assessing the functional status of heart. It is controlled by autonomic nervous system (ANS) through HR and SBP. Increase in RPP under stressed condition implies the normal buffering function of ANSand good coronary perfusion. In the present study, RPP increased significantly in males and non-significantly in females after physical stress, implying that ANS buffering function is better in males than in females. We conclude that RPP is a good index to assess cardiovascular competency in stress which may help to determine the intensity and duration of exercise in developing physical fitness and in patient-care without overloading the heart.
Is blood pressure a determinant of fitness?
Blood pressure and HR is a determinant of physical fitness since they both increase during exercise, but not at the same pace [20,24,25].

Abstract
Inability to supply oxygen to the myocardium when demand is high appears to be related to several cardiovascular events, including transient myocardial ischemia, acute myocardial infarction, and sudden death.
Evaluating effects of chronotherapy on heart rate and rate-pressure product
A recent study assessed the impact of chronotherapy on BP, heart rate, and rate-pressure product, particularly during the early morning hours, in patients with hypertension.
Clinical implications
The primary differences between the two treatment groups were the effects on heart rate and rate-pressure product. COER-verapamil reduced both these hemodynamic parameters during the early morning hours when heart rate and BP typically rise and when the incidence of cardiovascular events peaks ( Figure 5 ).
