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) |
|
❑ In suspicion of structural heart disease in patients presented with bradycardia or bundle branch block, transesophageal echocardiography, computed tomography, cardiac magnetic resonance imaging (MRI),or nuclear imaging is recommended |
| 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 |
