What Happens In A Single Heartbeat. These are extra beats that occur singly or can occur in patterns alternating with the normal heartbeat. During a cardiac cycle, both the atria and ventricles undergo periods of contraction ( systole ) and relaxation ( diastole ), which are.
This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body.

Systole, Period Of Contraction Of The Ventricles Of The Heart That Occurs Between The First And Second Heart Sounds Of The Cardiac Cycle (The Sequence Of Events In A Single Heart Beat ).
A heart arrhythmia occurs when the electrical signals that tell the heart to beat don’t work.
