Ejection fraction will be measured by echocardiography.
Ejection fraction is the percent of blood pumped by the heart. An ejection fraction 70% means that from 100% of blood inside the ventricle, 70% will be sent out and 30% will still be found in the heart.
Echocardiography can be used to measure the ejection fraction of the heart and it was less invasive than other methods.
