Describes sequence of events that occur in the heart over one beat. The phonocardiogram represents the heart sounds throughout the cardiac cycle. Role of atrial contraction in ventricular filling.

The pressures in the chambers change.

Consists of two phases divided into six stages. The cardiac cycle diagram shown to the right depicts changes in aortic pressure (ap), left ventricular pressure (lvp), left atrial pressure (lap), left ventricular volume (lv vol), and heart sounds during a single cycle of cardiac contraction and relaxation. Various maneuvers (eg, inspiration, valsalva, handgrip, squatting, amyl nitrate inhalation) can modify cardiac physiology. Systole iѕ thе nаmе givеn tо a period whеn cardiac muscle contract tо саuѕе blood ejection frоm thе rеѕресtivе chamber tо another.

It is comprised of a period of contraction (systole) and blood returning to the heart will flow into the atria and ventricles as the pressure in them is lower (due to low volume of blood).
