WebNov 29, 2024 · The electrical signals, or impulses, of the heart are generated by specialized tissue called the sinoatrial (SA) or sinus node ( figure 1 ). The sinus node is sometimes called the heart's "natural pacemaker." Each time the sinus node generates a new electrical impulse; that impulse spreads out through the heart's upper chambers, called the ... WebNormal cardiac activity begins in the sinus node, where cells with intrinsic automaticity act as pacemaker cells. Electrical wave fronts then spread across the atria to the atrioventricular (AV) node, which they pass through to enter the His-Purkinje system to rapidly spread to and depolarize the ventricles ( Figure 1 ).
