Ejection fraction measures how well your heart pumps blood out of the ventricles. Learn about left and right ventricular ejection fraction, normal ranges, abnormal levels and conditions that affect ejection fraction.
14 de jun. de 2023 · Ejection fraction (EF) is a percentage of blood pumped out by the left ventricle with each contraction. Learn how EF is measured, what is normal and abnormal, and how it relates to heart failure types and diagnosis.
17 de feb. de 2023 · El término “fracción de eyección” es la cantidad de sangre, expresada en un porcentaje, que se bombea de un ventrículo lleno con cada latido del corazón. La fracción de eyección generalmente se mide solo en el ventrículo izquierdo. El ventrículo izquierdo es la cavidad de bombeo principal del corazón.
17 de feb. de 2023 · Ejection fraction is the percentage of blood leaving the heart with each contraction. Learn how it's measured, what it means and what factors can affect it.
25 de jun. de 2023 · Ejection fraction is a measurement of how well your heart pumps blood. Learn about the normal range, the causes and symptoms of low ejection fraction, and the treatment options for heart failure.
24 de abr. de 2023 · Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at the end of diastole (end-diastolic volume).
5 de may. de 2024 · Definition. Three main phenotypes describe HF according to the measurement of the left ventricle ejection fraction (EF), and the differentiation between these types is important due to different demographics, comorbidities, and responses to therapies: Heart failure with reduced ejection fraction (HFrEF): EF less than or equal to 40%
