electrical impulses from the heart muscle cause your heart to beat (contract) .
this electrical signal begins in the sinoatrial(SA) node , located at the top of the hearts upper right chamber (the right atrium) . this sa node is called the hearts natural pacemaker.

The pacemaker is located in the 'wall of the right atrium', both ventricles and septum.
EXPLANATION:
The sino-atrial node or the right wall of the atrium present near the opening of 'superior vena cava' contains the pacemaker. Other locations of the pacemaker cells include atrio-venticular node located between the left atrium and right ventricle, along the 'inter-ventricular septum' and the Purkinje fibres in the "inner ventricular walls" of the heart beneath the endocardium.
