Webb27 juli 2024 · The parts of the heart conduction system can be divided into those that generate action potentials (nodal tissue) and those that conduct them (conducting fibers). Although all parts have the ability to generate action potentials and thus heart contractions, the sinuatrial (SA) node is the primary impulse initiator and regulator in a healthy heart. Webbprecursors of the Purkinje network (de Jong et al. 1992, Sedmera et al. 2004), it is clear that not all the trabeculae will turn into Purkinje fibers – in fact, the majority will form trabeculae carneae, or “meaty” trabeculations composed largely of working myocardium, that we find on the inside of the ventricles. As noted above, our
WebbThe Purkinje fibers transmit the signals more rapidly to stimulate contraction of the ventricles. [2] The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. Webb1 juli 2009 · In a 2-month-old female savannah kitten that died unexpectedly, the pathologic findings of significance were restricted to the heart and included abnormal Purkinje fibers and biventricular myocardial trabeculation or noncompaction. The Purkinje fibers were large, angular, and tightly packed. They contained few disorganized myofibrils among a …
