When blood and air is tranferred into the heart, the heart has to start beating unless we are dead.
The rhythmic beating of the heart is maintained by the Sinoatrial node (80-100 beats/minute), the Atrioventricular node (40-60 beats/minute) or the Purkinje fibers (20-40 beats/minute). It involves the membrane potential of specialized myocardial cells in these parts. Once regions of the heart are fully depolarized (such as the ventricles), contraction follows. Immediately following depolarization comes repolarization, and thus the cycle can repeat itself.
