Lets look at how the conduction system related to what we record on the ECG.The Purkinje fibers conduct the impulse to all parts of the ventricles, causing contraction (Guyton, 1982).

The impulse continues through the AV bundle and down the left and right bundle branches of the Purkinje fibers. The impulse is delayed slightly at this point to allow complete emptying of the atria before the ventricles contract. The AV node is responsible for conduction of the impulse from the atria to the ventricles. The impulse travels from the SA node through the internodal pathways to the atrioventricular node (AV node). It is crescent shaped and about 3 mm wide and 1 cm long. This node is located along the posterior wall of the right atrium right beneath the opening of the superior vena cava. The sinoatrial node (SA node) is the pacemaker where the electrical impulse is generated.The left side of the heart receives (from the lungs) and pumps arterial blood to the body. Top is the right and left atria Bottom is the right and left ventricles The right side of the heart receives and pumps venous blood to the lungs. The heart is divided into four chambers, but it functions as a two sided pump. The excitatory and electrical conduction system of the heart is responsible for the contraction and relaxation of the heart muscle. In an adult with a healthy heart, the heart rate is usually about 72 beats per minute.
