Overview
Echocardiography can be performed in the patient with ventricular tachycardia to rule out structural abnormalities such as a right ventricular cardiomyopathy and silent ischemia on stress testing. Coronary arteriography is often performed in the patient with ventricular tachycardia to rule out obstructive coronary artery disease.
Echocardiography
Echocardiography is an available and helpful modality for diagnosis and predicting the underlying causes of ventricular tachycardia and sudden cardiac arrest. Findings on an echocardiography include:
- Global and regional myocardial function
- Assessment of valvular structural and functional disease
- Evaluation of congenital heart disease
- Determination of Cardiomyopathy, heart failure, prior MI[1]
- There is no difference between modalities (echocardiography, radionuclide angiography, contrast angiograms) for evaluation of LVEF and determining the ICD implantation.[2]
