i dont understand the difference btw heart attach and heart block — Preceding unsigned comment added by 59.96.27.195 (talk) 15:25, 6 April 2008 (UTC)[reply]

[Purkinge fibers] and cells are highly adapted [sympathetic] nerves and branches that sweep electrical signal down to the apex of the heart and back up again. The "weeping willow" dissemination of this sympathetic signal selectively recruits cardiac muscle mass to initiate the force of [systole], or the pumping of blood out of the heart to the lungs and body. Histologically, the Purkinge fibers and cells are of interest in that they begin in the [Sinoatrial Node] and depolarize the atria [Atrial Systole] and then collectively center and transit the [Atrioventricular Node]. Once delivered to the ventricles in this manner these large bundles of purkinge fibers cannnot ever (WPW, LGL noted) penetrate the collagen ceiling of ventricular mass defined as the [Central Body of the Heart] [Cardiac Skeleton]or valve ring strata therefore ensuring systole is spent in the ventricles. The Purginge network of sympathetic cardiac polarization bears the standard electrical signal of PQRS on an [EKG]. The Purkinge tree is balanced by returning [parasympathetic] innervation represented by the cardiac branches of the [Vagus] nerve and the thoracic [Spinal Accessory]nerves.--Lbeben (talk) 01:02, 23 July 2008 (UTC)[reply]

The introduction to this article states that PFs are in the inner ventricular walls of the heart, but in the next section it discusses atrial PFs. Are purkinje fibers in both atria and ventricles, or just ventricles?? -Bobsagat —Preceding unsigned comment added by Bobsagat (talk • contribs) 20:02, 1 September 2009 (UTC)[reply]

Dubious

This could just be because the cardiology jargon is over the head of a lay-person (me), but it appears to say the Purkinje fibers do not have any pacemaker activity of their own and only conduct. This is contradicted by this page, other articles on wiki, a google search of "purkinje fibers" with one from a university here[1]. —Preceding unsigned comment added by 87.112.30.23 (talk) 21:35, 15 January 2011 (UTC)[reply]

The above issue has now been corrected, with a reference. Thanks! Bibeyjj (talk) 14:55, 13 November 2020 (UTC)[reply]

Pronunciation

Are we really giving it as purKINjee?? It comes from Czech Purkyně, which is /pʊrˈkinje/, poor-KEEN-ye. Pronouncing the j as a 'dzh' is nonsense. — Preceding unsigned comment added by 82.17.188.36 (talk) 13:13, 19 June 2020 (UTC)[reply]

That's how English speakers pronounce it, as you can hear here. It may make little sense from an etymological point of view, but as an encyclopedia we only describe how words are pronounced, not how they should be pronounced (which prompts the question, according to whom?), as do dictionaries such as the one cited.
