Middle English (Scots) carne, from Scottish Gaelic carn; akin to Old Irish & Welsh carn cairn
Ejection fraction is commonly measured by an echocardiogram and serves as a general measure of a person's cardiac function. Ejection fraction is typically low in patients with the systolic form of congestive heart failure.
When is ejection fraction (EF) low enough to consider heart transplantation? I have what they say is severe cardiomyopathy. My last ejection fractions (EF) were between 20-25, which fell in a 2 year period from 30-35. I do have an ICD pump.
