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.
1 The atria should contract (& finish contracting) before the ventricles contract. This occurs because of AV nodal delay (that is, the impulse travels rather slowly through the AV node & this permits the atria to complete contraction before the ventricles begin contraction).
