What is a common feature of Ventricular Tachycardia?

Ventricular Tachycardia (VT) is characterized by the presence of wide and often bizarre QRS complexes on an electrocardiogram (ECG). These complexes are wider than normal due to the fact that the impulse is originating from the ventricles rather than from the normal conduction pathways. In VT, the heart is beating quickly, often at a rate of 150 beats per minute or higher, and the irregular shape of the QRS complexes is a direct result of the ventricles depolarizing in an abnormal manner.

The presence of wide and bizarre QRS complexes is a hallmark indicator of the ventricular origin of the arrhythmia. This feature differentiates it from other tachycardias that may present with narrow QRS complexes where the impulse is conducted normally through the ventricles. Understanding this characteristic is crucial for proper diagnosis and treatment of the condition.
