Sinoatrial node is known as pacemaker of the heart. It helps in the generation and conduction of heart beat. It is located in the walls of the right atria just below the opening of superior venacva. The sympathetic nerves release the neurotransmitters and activates the SA node and generates electric impulse which is conducted as heart beat through out the heart. 

When the cardiac pacemaker in a patient fails to function normally a artificial pacemaker is implanted at the site of SA node. It is a medical device which uses electrical impulse, generated by electrodes to contract the heart muscles, and regulate the heart beat.
