Albert Frank Stanley Kent (1863 – 1958) was an English physiologist eponymously associated with the bundle of Kent, an alternative conduction pathway between the atria and ventricles, first described in 1913.
Professor A. F. Stanley Kent, investigated the field of ‘industrial fatigue’ in munitions and other industrial workers, attributed to ‘muscular and mental fatigue, worry, bad atmosphere, ill health and starvation‘. Professor Kent also reported on the ‘Monday effect‘ that affects ‘men and women who misuse their leisure by excessive drinking or other dissipation’.

Bundle of Kent (1893, 1913)
An accessory pathway consisting of conductive tissue that dissects the atrioventricular fibrous skeleton providing a direct connection between the atria and the ventricles bypassing the AV node.
In 1893, Kent demonstrated that in the newborn rat there are muscular connections between atria and ventricles, not only in the septum, but in the right and left lateral walls of the heart. In the young rabbit, such communications are found in the right lateral wall and the medial part of the left A-V ring, in addition to the septum. Similar connections are also found in the guinea pig and hedgehog. In the monkey, however, only here and there do muscular fibers pass from atria to ventricles.
At about the same time, Wilhelm His Jr. (1863–1934) described the atrioventricular bundle (bundle of His), and believed this to be the only communication between atria and ventricles.
In 1913, Kent described, in the human heart, a communication between the right atrium and ventricle, in the lateral aspect. In 1914, in this region, he described a right lateral atrioventricular node of specialized tissue which communicated with both
atrium and ventricle.
The muscular connection between auricle and ventricle in the heart of man is not single and confined to the A.V. bundle, but it is multiple. One point at which a muscular connection between auricle and ventricle exists is situated at the right margin of the heart. The coordinated action of the chambers of the heart is to some extent dependent upon the integrity of muscular connections other than that which exists in the A.V. bundle. It is proposed, for purposes of identification, to refer to the connection described as the “right lateral” connection.Kent AFS 1913
Although it is widely accepted that the atrioventricular bundle was discovered by Wilhelm His Jr. in 1893 (Bundle of His) some argue it was first described by Kent at a meeting in 1892.
New research on ‘industrial fatigue’; Nature and The Lancet report on research by Professor A. F. Stanley Kent, Chair of Physiology, into the new field of ‘industrial fatigue’ in munitions and other industrial workers, which is caused by ‘muscular and mental fatigue, worry, bad atmosphere, ill health and starvation’. Professor Kent also reports on the ‘Monday effect’ that affects ‘men and women who misuse their leisure by excessive drinking or other dissipation’.
We all know how greatly the mental condition affects digestion. Pain, and grief, and worry – more particularly worry – may lead to acute and lasting indigestion, with consequent fatigue and loss of vigour. Unfriendly supervisors have been quoted as a cause of serious loss of output. Dazzling lights, improperly arranged, by straining and irritating the workers’ eyes, may lead to a mental condition incompatible with good digestionAFS Kent in ‘Industrial Fatigue’, 1919
