Answer:

The heart's electrical system

Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart: SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node.
