Ejection fraction (EF) measures the amount of blood pumped out of your heart's lower chambers, or ventricles. It's the percentage of blood that leaves your ventricle when your heart contracts. The ...

Ejection fraction refers to how much blood the heart pumps out during a contraction. An abnormal ejection fraction can be a sign of heart failure. Some people might need treatment to improve their ...

Ejection fraction is a measurement doctors can use to help diagnose heart failure. A normal range is between 52% and 72% for males and between 54% and 74% for females. An ejection fraction that’s ...

Q: Can you tell me about ejection fractions? My wife’s heart doctor recently told us that her heart is weak, and she has a low ejection fraction. He did not discuss this much, but he has put her on ...

Ejection fraction (EF) measures how well the heart pumps blood. A normal ejection fraction is between 55% to 70%. A low ejection fraction can be a sign of heart failure. Ejection fraction (EF) ...

Heart failure with preserved ejection fraction (HFpEF) is a condition in which the heart does not fill with blood properly. In HFpEF, the heart can pump normally, but the heart is stiff and cannot ...

Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function. In this study, we examined whether biventricular pacing is ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...
