Cardiac reserve

From Wikipedia, the free encyclopedia

Cardiac reserve refers to the difference between the rate at which the heart pumps blood and its maximum capacity for pumping blood at any given time. A measurement of the cardiac reserve may be a health indicator for some medical conditions. Cardiac reserve may be 4-5 times greater than a resting value for a healthy person.

Measurements[]

Cardiac reserve has been measured in different ways over the history of the test.[1]

It is possible to make a non-invasive measurement of cardiac reserve.[2]

Significance[]

A measure of cardiac reserve can help predict the likelihood of heart failure when indicated.[3]
