Unusual course of congenital complete heart block in an adult: A case report

Figure 1 Electrocardiography on admission on admission. Complete atrioventricular block with junctional escape at 48 beats per minute.

Figure 2 Cardiovascular contrast-enhanced magnetic resonance imaging. A: Cardiac magnetic resonance image (MRI) of the systolic phase of four chambers and axial view showed normal atrioventricular size and myocardial function; B: Cardiac MRI of the diastolic phase of four chambers and axial view showed normal atrioventricular size and myocardial function; C: T2-weighted image did not reveal any myocardial edema; D: Late gadolinium enhancement revealed no definite area of hyperenhancement to suggest myocardial fibrosis.

Figure 3 Electrocardiography at 28 years of follow-up. Complete atrioventricular block with junctional escape at 42 beats per minute.
