Overview
Echocardiography is useful for finding the underlying structural heart disease including left ventricular systolic dysfunction in patients with atrioventricular block, especially in the presence of LBBB pattern on resting ECG.
Echocardiography
- Echocardiography is useful for finding the underlying structural heart disease including left ventricular systolic dysfunction in patients with atrioventricular block, especially in the presence of LBBB pattern on resting ECG.
- Echocardiography can be initial evaluation in patients presented with bradycardia associated with atrioventricular block for finding the underlying cardiomyopathy, valvular heart disease, congenital anomalies, tumors, infections, infiltrative processes, immunologically mediated conditions, and diseases of the great vessels and pericardium especially with manifestation of cardiac syncope.[1]
| Recommendations for Echocardiography in Bradycardia or Conduction disorder |
| Echocardiography (Class I, Level of Evidence B): |
|
❑ Echocardiography is recommended in patients with newly identified LBBB, second-degree Mobitz type II atrioventricular block, high-grade atrioventricular block, or third-degree atrioventricular block with or without apparent structural heart disease or coronary artery disease |
| Echocardiography ( Class IIa, Level of Evidence B) : |
|
❑ Echocardiography is recommended in suspicion of structural heart disease in patients presented with bradycardia or conduction disorders other than LBBB, second-degreeMobitz type II atrioventricular block, high-grade atrioventricular block, or third-degree atrioventricular block |
Abbreviations:
LBBB: Left bundle branch block
