What is the significance of the AVR and why is it a useful parameter to measure when a person changes their activity level?

Solution

Avr is defined as the arotic valve replacement.. It is carried out in those patients whose arotic valve in the heart is not able to work properly due to which the valve is not able to close the incoming and outgoing blood blow through it inside the chamber of the heart..

It is carried in those situations where the arotic valve has lost its flexibility, become leaky or gets blocked..!!

So in that case natural is replaced by artificial one..

It is being clearly indicated and proved that the physical activity increase the rate of heart beat or decrease the rate of heart beating which also increase or decrease the amount of blood entering into the heart depending on the activity level.. Hence to check the proper functioning of the AVR activity level could be checked the response could be checked according to it
