In second degree type II AV nodal block (a.k.a. Mobitz Type II AV block), the AV node becomes completely refractory to conduction on an intermittent basis. For example, three consecutive P waves may ...

The study found significant improvements in both the 6-minute hallway walk test and ejection fraction (EF) in patients receiving a BVP device (also referred to as cardiac resynchronization therapy ...

Atrioventricular reentrant tachycardia occurs when a reentrant circuit is present outside of the AV node through an abnormal conduction pathway that connects the atrium to the ventricles. If an action ...

The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium.

I am interested in elucidating the function of small membrane proteins (ion channels and exchangers) responsible for generating electrical activity of cells in the heart. I have a long-standing ...

An international team of scientists from Manchester, Montpellier and Copenhagen have identified why some endurance athletes experience a heart rhythm disturbance called ‘heart block’. The University ...
