The atria are two different heart sections/chambers located at the upper region of the heart.
The atria play a fundamental role during the during heart cycle, i.e. they act as blood reservoirs in the systole.
In conclusion, the purpose of the delay in the conduction of the action potential is to allow the atria to complete their contraction.
