Atrioventricular block is a condition in which the transmission of electrical impulses in the heart from the atria to the ventricles is partially or completely interrupted. Atrioventricular block is classified into 3 different grades, of which 3rd degree atrioventricular block is the highest degree of atrioventricular block and can cause many dangerous complications, even sudden death.

Atrioventricular block (AV block) is a conduction disorder from the atria to the ventricles that causes arrhythmias of many causes. Depending on the block level, there are different dangerous properties.

Atrioventricular block is a partial or complete obstruction of the conduction of electrical impulses from the atria to the ventricles due to anatomical or functional impairment. If the disease is not detected and treated early, it will progress to higher stages, causing arrhythmias and various dangerous complications.
