Effective measures for primary prevention  of atrioventricular  block include treatment of hypertension and maintenance of normal blood glucose levels. Atrioventricular (AV) block is a common reason for pacemaker implantation, and the number of pacemaker implantations is increasing. Atrioventricular block most commonly occurs in the absence of significant cardiac disease and is generally attributed to idiopathic fibrosis of the conduction system. By definition, the cause of that fibrosis remains unknown without primary prevention strategy.
