A Case of Complete Atrioventricular Block Associated with Pathogenic Variants in the SCN5A and GATA4 Genes

Complete AV Block with SCN5A and GATA4 Variants

Abstract

Summary

A 27-year-old male patient undergoing regular hemodialysis three times per week did not miss any dialysis sessions during the week of referral. He presented with dizziness and was found to have complete atrioventricular (AV) block on electrocardiography. The patient was admitted to the intensive care unit, where a temporary pacemaker was implanted. Subsequently, a dual-chamber permanent pacemaker was implanted. No electrolyte imbalance was detected. Because of suspected congenital anomalies, the patient underwent a thorough evaluation, which revealed pathogenic variants in the SCN5A and GATA4 genes.
