Overview
Transesophageal echocardiography, computed tomography, cardiac magnetic resonance imaging (MRI), or nuclear imaging are other advanced imagings that can be used in suspicion of structural heart disease in patients presented with bradycardia or bundle branch block.
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 |
