Risk calculators and risk factors for Ventricular tachycardia echocardiography |

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.
ACC/AHA/ESC 2006 Guidelines - Ventricular Arrhythmias - Left ventricular function and imaging (DO NOT EDIT) [1]
| Class I |
| "1. Echocardiography is recommended in patients with ventricular arrhythmias who are suspected of having structural heart disease. (Level 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 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 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 B)" |
| Class IIa |
| "1. MRI, cardiac computed tomography (CT), or radionuclide angiography can be useful in patients with ventricular arrhythmias when echocardiography does not provide accurate assessment of LV and RV function and/or evaluation of structural changes. (Level B)" |
| "2. Coronary angiography can be useful in establishing or excluding the presence of significant obstructive CHD in patients with life-threatening ventricular arrhythmias or in survivors of SCD, who have an intermediate or greater probability of having CHD by age, symptoms, and gender. (Level C)" |
| "3. LF imaging can be useful in patients undergoing biventricular pacing. (Level C)" |
