Cardiac Cycle

Cardiac Cycle

Cardiac Cycle. The two atria contract at the same time, then they relax while the two ventricles simultaneously contract. The contraction phase of the ventricle chambers is called systole . The relaxation phase is called diastole .

The Cardiac Cycle

The Cardiac Cycle

The Cardiac Cycle. Cardiac Cycle. The cardiac cycle is one complete heart beat – a contraction and relaxation of each heart chamber; 1 cycle = 0.8s 2 basic phases: Diastole: ventricles relax to fill with blood Systole: Ventricles contract to push blood into arteries.
