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 the underlying causes of ventricular tachycardia. 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
- LVEF evaluation as the strong predictor of SCD and mortality
- There is no difference between modalities (echocardiography, radionuclide angiography, contrast angiograms) for evaluation of LVEF and determining the ICD implantation.

| Class I |
| "1. Echocardiography is recommended in patients with ventricular arrhythmias who are suspected of having structural heart disease. (Level of Evidence B)" |
| "2. Echocardiography is recommended for the subset of patients at high risk for the development of serious ventricular arrhythmias or SCD, such as those with dilated, hypertrophic, or RV cardiomyopathies, AMI survivors, or relatives of patients with inherited disorders associated with SCD. (Level of Evidence B)" |
| "3. Exercise testing with an imaging modality (echocardiography or nuclear perfusion single-photon emission computed tomography (SPECT)) is recommended to detect silent ischemia in patients with ventricular arrhythmias who have an intermediate probability of having CHD by age, symptoms, and gender and in whom ECG assessment is less reliable because of digoxin use, LVH, greater than 1-mm ST segment depression at rest, WPW syndrome, or LBBB. (Level of Evidence B)" |
| "4. Pharmacological stress testing with an imaging modality (echocardiography or myocardial perfusion (SPECT)) is recommended to detect silent ischemia in patients with ventricular arrhythmias who have an intermediate probability of having CHD by age, symptoms, and gender and are physically unable to perform a symptom limited exercise test. (Level of Evidence B)" |
