Best answer: What is the electrical control of heart rhythm?

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. The electrical activity spreads through the walls of the atria and causes them to contract.

How does the heart maintain rhythm?

Your heart has a special electrical system called the cardiac conduction system. This system controls the rate and rhythm of the heartbeat. With each heartbeat, an electrical signal travels from the top of the heart to the bottom. As the signal travels, it causes the heart to contract and pump blood.

What controls the conduction system of the heart?

Cardiac conduction system: The electrical conduction system that controls the heart rate. … Among the major elements in the cardiac conduction system are the sinus node, atrioventricular node, and the autonomic nervous system. The sinus node is the heart’s natural pacemaker.

What is the heart’s electrical system called?

The SA node (called the pacemaker of the heart) sends out an electrical impulse. The upper heart chambers (atria) contract. The AV node sends an impulse into the ventricles. The lower heart chambers (ventricles) contract or pump.

How the heart contracts step by step?

The heartbeat happens as follows:

  1. The SA node (called the pacemaker of the heart) sends out an electrical impulse.
  2. The upper heart chambers (atria) contract.
  3. The AV node sends an impulse into the ventricles.
  4. The lower heart chambers (ventricles) contract or pump.
