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.
The amount your left ventricle does pump out per beat is called the ejection fraction. It's X% (the amount pumped out) of the total amount of blood in the ventricle per heart beat. If your heart pumps out 55% or more of the blood in your left ventricle on each beat, you have good heart function. When it falls below 55% on each beat, you're slipping. That means your heart muscle is too weak to force as much blood out on each contraction as it should. Now, if your EF sounds bad, don't despair.
