Purkinje fiber

One of the specialized cardiac muscle fibers, part of the impulse-conducting network of the heart, that rapidly transmit impulses from the atrioventricular node to the ventricles.

[After Johannes Evangelista von Purkinje (1787-1869), Bohemian physiologist.]

Further, a previous study showed that the insertion sites were abundant with Purkinje fibers and cholinesterase-containing nerve fascicles, which gave rise to the possibility that a mechanical stretch of RV might influence its electrophysiological properties.[8] In addition, the APM, also a potential substrate for idiopathic ventricular arrhythmia, is anatomically connected with MB, and ablation of the ventricular insertion to papillary muscle proved a perfect target for PM-origin ventricular arrhythmia.[9]
