The infrahisian system, which comprises the main bundle branches, fascicles, and the Purkinje network, is the source of most clinically important heart block in adults and is measured by the His-ventricular interval on an electrophysiological study.
During ipsiventricular pacing at least, ectopic excitation of the heart ventricles with the "rich" Purkinje network behaves like one of the mammalian ventricles with the subendocardial Purkinje network.
On the other hand, participation of the Purkinje network in ventricular activation of the avian heart during ventricular pacing can not be fully denied for following reasons: 1) the obtained values of duration of activation during ventricular pacing (Table 1) are 2-4 times less than values (50-60 ms) calculated taking into account the conduction velocity in the contractile myocardium of -0.
