Overview

In the presence of atrioventricular block and evidence of structural heart disease, cardiac imaging is considered. However, routine cardiac imaging is not recommended in patients with asymptomatic first-degree atrioventricular block and no clinical evidence of structural heart disease.

Other imaging findings

Recommendations for imaging study in Bradycardia or Conduction disorder

Advanced imaging : (Class IIa, Level of Evidence C)

Cardiac imaging : (Class III, Level of Evidence B)

❑ Routine cardiac imaging is not recommended in patients with asymptomatic sinus bradycardia or first-degree atrioventricular block and no clinical evidence of structural heart disease
