Disease relevance of Heart Conduction System

• In contrast, the VACT in patients with WPW syndrome remained unchanged during ventricular pacing at rates of 145/min and more before and after atropine, indicating the retrograde conduction was taking place through the Kent bundle [1].

High impact information on Heart Conduction System

• Complete serial section (SS) of the CS in both cases revealed an anterior CS and a Kent bundle in the posteroseptal wall of the morphologic right ventricle (MRV) [2].
• Increased immunoexpression of atrial natriuretic peptide in the heart conduction system of the rat after cardiac sympathectomy [3].
• Neuropeptide Y-like immunoreactivity in relation to the distribution of sympathetic nerve fibers in the heart conduction system [4].
• Atrial natriuretic peptide in the innervation of the bovine heart conduction system: relationship with substance P and autonomic innervation--immunohistochemical studies [5].
• Localization of angiotensin AT1 receptors in the rat heart conduction system [6].

Associations of Heart Conduction System with chemical compounds

• Flecainide plasma concentrations correlated to inhibition of a bundle of Kent [7].
• A histochemical study of some enzymes of glucose metabolism was performed on the heart conduction system of rat, dog, rabbit, pig, calf and lamb [8].
• The dangerous form of WPW (rapid conduction in the Kent bundle > 240/min in the control state or > 300/min after isoproterenol + AF induction) occurred, respectively, in 3 (21%), 9 (27%), 4 (27%), 1 (6%), and 3 (23%) patients [9].
• Atropine influence was negative on QRS complex of pattern W i2 cases showing the co-existence of Kent bundle and James fibers or exclusive Kent bundle conduction [10].

Gene context of Heart Conduction System

• Division of the Kent bundle was successful in 31 patients, but 2 deaths occurred from cardiomyopathy [11].
• The importance of the high glycogen content and the high phosphorylase activity in the heart conduction system was discussed [8].
