Key Concepts

Diastole

Diastole is the phase of relaxation in the cardiac cycle where the heart chambers fill with blood. This period follows systole and allows the heart muscle to rest and energy to be replenished before the next contraction.

Atrioventricular Coordination

Atrioventricular coordination is a critical aspect of the cardiac cycle that ensures the atria contract and empty their blood into the ventricles before the ventricular contraction begins. This sequential timing optimizes the efficiency of blood flow and maintains proper heart function.

Cardiac Cycle

The cardiac cycle is the series of mechanical and electrical events that repeat with every heartbeat, including the contraction and relaxation phases of the heart's chambers. It ensures the continuous flow of blood through the heart, lungs, and body, and involves coordinated timing between atrial and ventricular activities.

Systole

Systole refers to the phase in the cardiac cycle when the heart muscles contract. This contraction causes the ejection of blood from the heart chambers—specifically, atrial systole pushes blood into the ventricles, and ventricular systole propels blood out to the pulmonary and systemic circulations.
