Peripheral Blocks

  • Paolo Alboni
Part of the Developments in Cardiovascular Medicine book series (DICM, volume 12)


We define peripheral block as a conduction disturbance localized below the main intraventricular pathways (bundle branches and fascicles), i.e. in the Purkinje and muscular fibers. As long ago as 1916, Oppeheimer et al. [1] hypothesized conduction defects located in the periphery of the intraventricular conduction system. Since then, however, few experimental [2–7] and clinical studies [8–19] have been performed and our knowledge on this topic is very limited. Peripheral blocks have been defined in various ways: block of the arborization [1], focal block [8] and parietal block [9]. In previous papers on peripheral blocks, most likely located in the left ventricular walls, we defined them as parietal blocks [14–16]. However, if we consider that these blocks can be present in any part of the heart, including the interventricular septum, the term ‘parietal’ is not adequate for all localizations, and the definition ‘peripheral block’ would, therefore, seem more appropriate.
