The function of the sinoatrial (SA) node is to act as the heart’s pacemaker and for this the cells of the SA node have to be electrically connected both to one another and also the atrial cells surrounding them. This chapter is concerned with the electrical coupling between cells in and around the SA node – it is shown that this is special, perhaps in order for the SA node to carry out its normal function. This chapter is written to complement our recent review of the functional and morphological organisation of the SA node (Boyett et al., 2000).
