Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. On the ECG, ventricular tachycardia can be defined as three or more ventricular ectopic beats occurring in a sequence at a rate more than 100 per minute. Another rare form of ventricular tachycardia is bidirectional ventricular tachycardia.

Three or more ventricular beats in a row at a rate above 100 per minute is termed ventricular tachycardia. Ventricular tachycardia lasting more 30 seconds or requiring termination earlier due to hemodynamic compromise is called sustained ventricular tachycardia. Either case, the treatment is ablation of the right bundle.

Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults. Ventricular arrhythmias during exercise can be documented in congenital long QT syndromes as well as in catecholaminergic polymorphic ventricular tachycardia.

Mechanism is thought to be due to sustained sympathetic stimulation, probably caused by dysfunction of insular cortex resulting in reversible neurogenic damage to the myocardium which could include contraction bands and subendocardial ischemia [2]. But the number of persons with lobar hemorrhage in that study was only 17%.

ECG in a person with persistent anginal pain for the past several hours showing significant ST segment depression anterolateral leads along with sinus tachycardia. ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum.

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. These are the conditions which have to be considered or excluded as they can sometimes manifest Brugada pattern on ECG.
