Human heart is myogenic in nature. It consists of sinoatrial node in the right atrium below the endodermis. this node initiates the electrical impulses in heart. As it is initiator it is also called pacemaker of heart. The atrioventricular node gathers the impulses and transmits them to the purkinje fibres via. bundle of his-tawara. As atrioventricular node collects all the impulses it is also called pacesetter of heart.
