Overview

Echocardiography has a highler yield where diagnosing syncope and presyncope is concerned, in patients with structural heart disease.

2018 ACC/AHA/HRS Guideline on the Evaluation and Management of Patients With Bradycardia and Cardiac Conduction Delay: Recommendations for Cardiac Imaging

Recommendations for Cardiac Imaging
"1. In patients with newly identified LBBB, seconddegree Mobitz type II atrioventricular block,high-grade atrioventricular block, or hirddegree atrioventricular block with or without apparent structural heart disease or coronary artery disease, transthoracic echocardiography is recommended. (Level of Evidence: B-NR[1]

2. In selected patients presenting with bradycardia or conduction disorders other than LBBB, second-degree Mobitz type II atrioventricular block, high-grade atrioventricular block, or third-degree atrioventricular block, transthoracic echocardiography is reasonable if structuralheart disease is suspected. (Level of Evidence: B-NR)[1]

3. In selected patients with bradycardia or bundle branch block, disease-specific advanced imaging (eg, transesophageal echocardiography, computed tomography,cardiac magnetic resonance imaging [MRI], or nuclear imaging) is reasonable if structural heart disease is suspected yet not confirmed by other diagnostic modalities. (Level of Evidence: C-LD)[1]

4. In the evaluation of patients with asymptomatic sinus bradycardia or firstdegree atrioventricular block and no clinical evidence of structural heart disease, routine cardiac imaging is not indicated. (Level of Evidence: B-NR)[1]"
