Ventricular tachycardia (VT) is a common arrhythmia seen in patients with heart failure (HF) and is now seen more frequently as these patients survive longer with modern therapies. In patients with a regular broad-complex tachycardia, ventricular tachycardia (VT) is highly likely in those with a history of myocardial infarction or congestive heart failure; the diagnostic tachycardia ECG is out of keeping with the right and/or left bundle branch block pattern . The rhythm may arise from ventricular myocardium, the distal conduction system, or both. Ventricular tachycardia (VT) is protean in form, duration, clinical setting, and prognosis. Clinical Presentation Haemodynamically stable Haemodynamically unstable e.g hypotension, chest pain, cardiac failure, decreased conscious level This is the most important classification clinically and influences immediate management. Fascicular ventricular tachycardia occurs in people aged less than 50 years of age, and predominantly in males. Incidence of Sudden Cardiac Death .e395 2.2.2.

There is no uniformly accepted classification of VT, and this arrhythmia may be subdivided using many factors, as noted in Table 8-1.Unfortunately, no single subcategory provides enough information for correct classification of all patients with VT, and in many instances there is substantial crossover. In most instances, the arrhythmia is ventricular tachycardia (VT), but polymorphic VT and ventricular fibrillation (VF) can also result in electrical storm. Keywords: Ventricular tachycardia 1.
