When an electrical impulse reaches the AV node, it is slowed for a brief period of time so that A blood can pass from the artria to the ventricles B the SA node can reset and generate another impulse C the impulse can spread through the Purkinje fibers D blood returning from the body can fill the atria11, 12 However, whether the atrial myocardium contains a similar conduction system has yet to be studied 13 Given that the atria do not have similar welldefined anatomic conductionFor instance, if there were too many impulses coming from the atria, and allowing all of them

This impulse spreads from its initiation in the SA node throughout the atria through specialized internodal pathways, to the atrial myocardial contractile cells and the atrioventricular node The internodal pathways consist of three bands (anterior, middle, and posterior) that lead directly from the SA node to the next node in the conductionVentricle (belly or pouch) cardiac conduction responsible for initiating electrical conduction of the heartbeat, causing the atria to contract and firing conduction of impulses to the AV node neurological tissue in the center of the heart that receives and amplifies the conduction of impulses from the SA node to the bundle of HisConduction system • This pause allows for the blood in the atria to move into the ventricles before the ventical contract • Impulses continue into the ventricle through the bundle of His which contain both right and left bundle branches • These impulses produce an electrical current which can be picked up by electrodes attached antibody

The electrical activity of the heart is controlled by a system of impulses generation and electrical conduction which includes the sinoatrial node (SA), the atrioventricular node (AV), the atrioventricular septum and the Purkinje fibers and which assures the cardiac automatism The SA node is located in the left atria's wallThe right ventricle pumps blood to the lungs and the left ventricle pumps blood around the body Important Information This booklet is intended for use by people who wish to understand more about electrophysiology studies The information comes from research and previous patients' experiences and should be used in addition Normally, the AV node is the gatekeeper between the atria and ventricles, slowing the electrical impulse momentarily before allowing it to continue to the ventricle Sometimes the node will even keep certain impulses from getting to the ventricle;
