Predictive factors of atrioventricular conduction disorders

Abstract

Atrioventricular conduction disorders represent an alteration in the normal function of the heart’s electrical conduction system, a system that connects the atria and ventricles through the atrio-ventricular node and the His-Purkinje system. Consequently, bradycardia can develop and lead to the occurrence of symptoms (dizziness, loss of consciousness, tachyarrhythmias, heart failure phenomena). Identifying patients at risk of developing atrioventricular conduction disorders will allow early interventions on risk factors and improvements in prognosis. This narrative review explores the risk factors that determine the development and progression of atrioventricular conduction disorders. We will discuss traditional risk factors (age, sex, arterial hypertension, ischemic cardiac disease, diabetes, chronic kidney disease), but also risk factors that are currently being researched (genetic predisposition and inflammatory markers). Finally, we will discuss the limitations and challenges of predicting risk factors for atrioventricular conduction disorders.
