The hearts electrical activity starts with the sino-atrial node in the right atrium, which sends its impulse to the rest of the heart causing contraction. However it the SA node fails there are still two backups, the AV Junction, and the purkinje fibers, however they are not able to send out impulses as fast and the contractions aren't as efficient.

What is the function of the intrinsic conduction system of the heart?
The intrinsic conduction system of the heart is responsible for initiating and coordinating the electrical impulses that regulate the heart's contractions. It includes specialized cardiac muscle cells that generate and conduct electrical signals to ensure the synchronized contraction of the heart muscle, allowing for efficient blood pumping.

How does an insect's heart beat?
