Lenegra disease is a rare heart disease that is characterized by impaired conduction of impulses in the heart muscle.
The name of the disease is associated with the name of the French cardiologist Jacques Lenaigre, who described it in 1933 using the term “idiopathic chronic blockade,” which translated from Latin means “causeless obstruction in the conduction of impulses.” Since then, the disease has also been known by the more popular name "isolated conduction system disease."
A characteristic feature of the disease is the presence of atrioventricular heart block, a pathology in which the electrical impulse is transmitted between the atria and ventricles with a delay. This may cause problems with normal operation
