Purkinje fiber

n.
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.]

Purkin′je fi`ber


n.
any of a network of impulse-conducting muscle fibers in the walls of the ventricles of the heart.
[after Jan Evangelista Purkinje (Czech Purkyně) (1787–1869), Czech physiologist, who discovered the fibers in 1839]

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]
