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.

QT prolongation and the occurrence of ventricular arrhythmias with exercise are another important aspect of exercise testing in children. Ventricular arrhythmias during exercise can be documented in congenital long QT syndromes as well as in catecholaminergic polymorphic ventricular tachycardia.

ICD is short form for implantable cardioverter defibrillator, used to automatically shock back the heart into action in case of life threatening ventricular arrhythmias. Moreover, the internal shocks given by CRT-D can be painful, though essential to save life in case of fast ventricular tachycardia or fibrillation.

This can be a source of cardiac arrhythmia as well. An important cause of arrhythmias in Ebstein’s anomaly is the presence of a right sided accessory atrioventricular pathway or WPW syndrome. This is one important cause of supraventricular tachycardia in Ebstein’s anomaly.

It can automatically detect life threatening ventricular arrhythmias and treat them, either with a shock or, sometimes by overdrive pacing. You may be knowing that one of the causes for inappropriate ICD shocks, is supraventricular arrhythmia, wrongly detected by the defibrillator as a ventricular arrhythmia and giving a shock.

In that study commonest ECG abnormalites were QTc prolongation followed by brady/tachycardia and then ST segment deviations [3]. Cerebrovascular damage can cause cardiac arrhythmias related to disinhibition of right insular cortex with resulting increased sympathetic tone.

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. This leads to shortening of action potential duration. With proper precautions, risk can be reduced.
