Webb7 apr. 2024 · Purkinje myocytes are the terminal component of the cardiac conduction system and interface in the ventricular myocardium with so-called “working” CMs, or alternatively with transitional CMs that then interface with working CMs. WebbThis impulse then travels through the atria, atrioventricular node (AVN), His bundle, and Purkinje fibers to reach the ventricles. During an invasive electrophysiological study (EPS), the conduction through the AVN is measured by the atrium-to-His (AH) interval, while the conduction through the His–Purkinje system (HPS) is measured by the His-to-ventricles …
