What special equipment is connected to the heart make it beat regularly?

There are no special equipments connected to the heart to make it beat regularly. The heart has its own electrical conduction system that controls and coordinates its beating. This system, consisting of specialized cells called the sinoatrial (SA) node, the atrioventricular (AV) node, and the bundle of His, generates and transmits electrical impulses that cause the heart muscle to contract and relax in a regular, rhythmic manner.
