WebJun 22, 2024 · The conduction system of the heart. 2. • The heart is endowed with a special system for (1) generating rhythmical electrical impulses to cause rhythmical contraction of the heart muscle (2) conducting these impulses rapidly through the heart. • When this system functions normally, the atria contract about one sixth of a second … WebName the elements of the intrinsic conduction system of the heart and describe the pathway of impulses through this system. The intrinsic conduction system, nodal system, contains special tissue found nowhere else in the body that causes heart muscle depolarization in only one direction – from the atria to the ventricles and it enforces a ... WebMay 8, 2024 · This group of muscle cells is called the cardiac conduction system. The main parts of the system are the SA node, AV node, bundle of HIS, bundle branches, and Purkinje fibers. Let's follow a signal through the contraction process. The SA node starts the sequence by causing the atrial muscles to contract. That's why doctors sometimes call it … phenylephrine tylenol
