Overview
Transthoracic echocardiography may be helpful in the diagnosis of the underlying diseases tend to third degree AV block. An echocardiography might show shreds of evidence in favor of cardiomyopathies and/or valvular heart diseases . In special case scenarios, transesophageal echocardiography is warranted and may help to diagnose etiologies such as valvular ring abscess. Furthermore, the left ventricular function can be determined using an echo, and provide evidences in favor of the placement of a pacemaker or defibrillator.
Echocardiography/Ultrasound
- Transthoracic echocardiography may be helpful in the diagnosis of the underlying diseases tend to third-degree AV block.
- An echocardiography might show shreds of evidence in favor of cardiomyopathies and/or valvular heart disease.
- In special case scenarios, transesophageal echocardiography is warranted and may help to diagnose etiologies such as valvular ring abscess.
- Furthermore, the left ventricular function can be determined using an echo, and provide shreds of evidence in favor of the placement of a pacemaker or defibrillator.
- Last but not the least, there are studies in favor of an association between inter-ventricular mechanical delay (IVMD) and cardiac function in pediatric complete heart block.[1]
