Congenital Complete Heart Block in Adults

Complete heart block occurs when atrial and ventricular contractions are not communicating, each beating, at their own pace. Therefore, it should be thoroughly investigated to ascertain its type. Congenital complete heart block (CCHB) might be unnoticed for a long time. CHB patients are prone to decreased perfusion related to symptoms of bradycardia and low cardiac output, which can lead to serious arrhythmias such as ventricular tachycardia, syncope, and sudden death. We searched PubMed and Google Scholar for CCHB in adults, implications, and outcomes. Accordingly further management of CHB is achieved by the implantation of a cardiac pacemaker, but it might be a challenging decision, particularly in asymptomatic patients.
