# What does rate pressure product mean

Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP).

## What does the rate pressure product indicate?

Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP).

## What is rate pressure product RPP reflective of?

It is an important indicator of ventricular function. RPP varies with exercise. The peak rate pressure product (PRPP) which gives an accurate reflection of the myocardial oxygen demand and myocardial workload is the RPP at peak of exercise.

## What is a normal rate pressure product?

Hemodynamic ResponseRPPHigh> 30 000High Intermediate25 – 30 000Intermediate20 – 25 000Low Intermediate15 – 20 000

## How do you find the rate pressure product?

The rate-pressure product (RPP) was calculated as the product of heart rate and systolic arterial pressure for both baseline and maximum measures.

## Why does rate pressure product increase during exercise?

Both HR and SBP are the most important variables determining changes in myocardial oxygen consumption between rest and exercise (10). HR, SBP and RPP increases with the increase workload on the heart to provide the adequate blood supply to the active myocardium during exercise.

## What does Valsalva maneuver do?

Performing the Valsalva maneuver causes an increase in intrathoracic pressure, leading to a reduction in preload to the heart. Cardiovascular changes occur during and after this maneuver due to baroreflex and other compensatory reflex mechanisms that are initiated by decreased preload.

## How do you know if you have good blood pressure?

1. a systolic pressure that’s above 90 mm Hg and less than 120 mm Hg, and.
2. a diastolic pressure that’s between 60 mm Hg and less than 80 mm Hg.

## 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.

When does cardiac drift occur?

Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress.

## What is RPP in treadmill test?

OBJECTIVE: To determine if the attainment of at least 85% of age-predicted maximal heart rate (APMHR), using the equation 220 – age, and/or at least 25,000 as the product of maximal heart rate and systolic blood pressure (rate pressure product, RPP) is an accurate indicator of exertion level during exercise stress …

## What is RPP a surrogate measure of?

Rate pressure product (RPP), calculated by multiplying SBP and HR, is a valid non-invasive surrogate measure of myocardial oxygen consumption. Coronary blood flow, cardiac workload and left ventricular hypertrophy have also been found to be relative to RPP.

## What is double product or rate pressure product?

The double product (DP), consisting of the systolic blood pressure (SBP) multiplied by the pulse rate (PR), is an index of myocardial oxygen consumption, but its prognostic value in the general population remains unknown.

## Is pulse rate the same as heart rate?

Your pulse rate, also known as your heart rate, is the number of times your heart beats per minute. A normal resting heart rate should be between 60 to 100 beats per minute, but it can vary from minute to minute.

## What is ischemic threshold?

The ischemic threshold was defined as the heart rate at which a 1 mm horizontal or downsloping ST segment depression appeared on a baseline treadmill symptom-limited exercise test.

## What does squatting do to preload?

Squatting forces the blood volume that was stored in the legs to return to the heart, increasing preload and thus increasing left ventricular filling.

## What's the Toynbee maneuver?

The “Toynbee maneuver”: pinching the nose and swallowing. Swallowing pulls open the eustachian tubes while the movement of the tongue, with the nose closed, compresses air which passes through the tubes to the middle ear.

## Do vagal maneuvers lower blood pressure?

This activates parasympathetic fibers, which quickly reduce the heart rate and blood pressure. Doctors sometimes refer to this effect as vagaling. The Valsalva maneuver reduces cardiac output, which is the amount of blood that the heart puts out with every beat.

## What determines myocardial oxygen demand?

Heart rate, contractility, and ventricular-wall tension are the three factors that determine myocardial oxygen demand. An increase in any of these variables requires the body to adapt to sustain adequate oxygen supply to the heart.

## How fast does your heart beat during a stress test?

Your target heart rate during a stress test depends on your age. For adults, the maximum predicted heart rate is 220 minus your age. So, if you’re 40 years old, the maximum predicted heart rate is 220 – 40 = 180.

## How long does the average person last on a stress test?

A stress test usually takes about an hour, including both prep time and the time it takes to do the actual test. The actual exercise test takes only around 15 minutes.

## Is 9 minutes on a treadmill stress test good?

In conclusion, for patients able to manage a 9-minute Bruce protocol, presence/absence of symptoms or electrocardiographic changes is a poor predictor of MPS findings. Irrespective of test findings, however, subsequent cardiac risk is extremely low.

## What is a good blood pressure by age?

AgeSBPDBP21-25120.578.526-30119.576.531-35114.575.536-40120.575.5

## Does coffee raise blood pressure?

Caffeine may cause a short, but dramatic increase in your blood pressure, even if you don’t have high blood pressure. It’s unclear what causes this spike in blood pressure. The blood pressure response to caffeine differs from person to person.

## When should you not take your blood pressure?

Each time you measure, take two or three readings to make sure your results are accurate. Your doctor might recommend taking your blood pressure at the same times each day. Don’t measure your blood pressure right after you wake up.

## Why is my HR so high when I run?

During cardio exercise such as running, your heart rate increases. Your heart rate while running can be a good measurement of how hard you’re working. As your pace and work rate increase, so does your heart rate. Blood circulates to your muscles so they can get the oxygen and nutrients they need to keep going.

## What is 75 of my max heart rate?

You want to stay within 50—75 percent of your maximum heart rate during exercise, depending upon your fitness level. To find your target heart rate, multiply your maximum heart rate by 0.50. This will give you the low range number. Then, multiply your maximum heart rate by 0.75.

## What is the highest oxygen consumption achieved during exercise called?

VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. This measurement is generally considered the best indicator of cardiovascular fitness and aerobic endurance.

## What is METs in TMT?

Exercise capacity is reported in terms of estimated metabolic equivalents of task (METs). The MET unit reflects the resting volume oxygen consumption per minute (VO2) for a 70-kg, 40-year-old man, with 1 MET equivalent to 3.5 mL/min/kg of body weight.

## How do you pass a treadmill stress test?

To pass your treadmill stress test i.e., to have a successful treadmill stress test, you need to avoid the following things for at least three hours before the test: Eating or drinking anything except water. Consuming anything that contains caffeine. Consuming tobacco in any form.

## What is MAP in blood pressure?

Introduction. The definition of mean arterial pressure (MAP) is the average arterial pressure throughout one cardiac cycle, systole, and diastole. MAP is influenced by cardiac output and systemic vascular resistance, each of which is influenced by several variables.
