A normal heart works in a synchronized rhythm between the top parts of the heart (the right and left atrium) and the bottom parts of the heart (the right and left ventricles).
In a normally working heart this impulse is generated by the sinoatrial node (SA node) which is located in the right atrium. When the heart beat is generated from the SA node the heart beats between 60-100 times per minute.
