endsystole
Endsystole refers to the final moments of ventricular systole, the phase of the cardiac cycle when the heart muscle contracts to eject blood. It is the point at which the ventricles have finished their contraction and are beginning to relax. This marks the transition from ejection to the subsequent relaxation phase, diastole.
During endsystole, the pressure within the ventricles is at its peak for that contraction cycle. The aortic
The duration of endsystole is very brief, as the heart rapidly moves into the relaxation phase. This
