WebNov 18, 2024 · For the heart to beat properly, the signal must travel down a specific path to reach the ventricles (the heart's lower chambers). When the heart's natural pacemaker is defective, the heartbeat may be too fast, too slow or irregular. Rhythm problems also can occur because of a blockage or abnormality of your heart's electrical pathways. WebThe electrical signals that travel through your heart conduction system cause your heart to expand and contract. These contractions control how blood flows through your heart. Ideally, the electrical conduction system keeps up a steady, even heart rate.

WebMar 24, 2024 · The heart has four valves. The tricuspid valve separates the right atrium and right ventricle. The mitral valve separates the left atrium and left ventricle. The pulmonary valve separates the right ventricle and the pulmonary artery. The aortic valve separates the left ventricle and aorta. WebThe conduction system of the heart. Normal excitation originates in the sinoatrial (SA) node, then propagates through both atria (internodal tracts shown as dashed lines). The atrial depolarization spreads to the atrioventricular (AV) node, passes through the bundle of His (not labeled), and then to the Purkinje fibers which make up the left ...
