These cells and nodes make up your heart conduction system pathway. Conduction System of the Heart Steps The main function of your heart’s conduction system is to contract and relax your heart, which causes your heart to beat and helps pump blood through your body. Each heartbeat is acco...
Heart conduction refers to the process by which electrical signals are generated and transmitted through specialized fibers in the heart, known as the cardiac conduction system, to coordinate the sequential contraction and relaxation of the heart muscle. These electrical events trigger muscle contractions...
Ventricular conduction system: Common AV bundle (of His): pathway within the IV septum by which the signal leaves the AV node Right and left bundle branches: The AV bundle divides into right and left bundles within the IV septum. Both run toward the apex. ...
pathway are used to prevent attacks, e.g.flecainide,sotaloloramiodarone. Do not useverapamilordigoxin, which mayincreaseconduction through the anomalous pathway. Electrical conversion restores sinus rhythm when the ventricular rate is very rapid. Radiofrequency ablation of aberrant pathways provides a ...

What is the Conduction System of the heart?The HeartThe heart is a muscle present in animals that is responsible for the pumping of blood throughout the body. This blood that is pumped through the heart enters unoxygenated before being pumped through the lungs and returning to the heart so ...

How does the pathway of electrical impulse conduction in the heart (intrinsic regulation of heart rate) work? What is the cardiac cycle in the he...
Conduction System Development In the primitive heart tube, all the cardiomyocytes are electrically coupled, and contractions proceed inperistaltic wavesfrom the inflow to outflow. However, in the four-chambered heart, the conduction system paces and orients the contractions of theatriaand ventricles to...
