Series of events that constitute a complete heartbeat. Pressure in heart changes. 70% of blood enters ventricles prior to atrial contraction. 30% of the returning blood is pushed in the ventricles.
An ejection fraction of 60% means that 60% of the total amount of blood in the left ventricle is pushed out with each heartbeat. What's normal? A normal heart's ejection fraction may be between 50% and 70%. You can have a normal ejection fraction reading and still have heart failure (called HFpEF or heart failure with preserved ejection fraction).
