Pediatric atrioventricular block

Atrioventricular block in children is also called atrioventricular block, which refers to the conduction delay in the normal conduction pathway between the atrioventricular block, part or all of the block. Common causes are organic heart disease, various myocarditis, digitalis, quinidine and other drugs; healthy athletes and heavy manual workers, as well as compression of the eyeball and carotid sinus, chest and neck tumors, and vagus nerve stimulation can also be seen. Cardiac block can occur anywhere on the conduction system, including between the sinoatrial node and the atrium, the atrial muscle, the atrioventricular junction, the atrioventricular bundle and its left and right bundle branches, Purkinje fiber network, and ventricular muscle. The most common childhood is atrioventricular block. Atrial agitation occurs in the atrioventricular junction, the atrioventricular bundle and its branches, and cannot be transmitted to the ventricle normally. Atrioventricular block can be divided into complete and partial blocks. Partialness can be divided into first degree and second degree. Completeness is also called third degree atrioventricular block. It is temporary, permanent or intermittent.
