Webculating a contractility parameter from isometric contrac- tions by making phase plots [15] can be applied to almost all patients [9]. It yields a parameter which is correlated with the … Web31 mei 2024 · Ejection fraction (EF) is a measurement, expressed as a percentage, of how much blood the left ventricle pumps out with each contraction. An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat.
