## **Core Concept**
Ventricular tachycardia (VT) is a type of abnormal heart rhythm, or arrhythmia, that originates in the ventricles. It is characterized by a series of premature ventricular contractions (PVCs) that occur at a rate of more than 100 beats per minute. The condition can be life-threatening and requires immediate medical attention.

## **Why the Correct Answer is Right**
The correct answer, , is associated with a feature that is not typical of ventricular tachycardia. In the context of VT, features often include a wide QRS complex (>120 ms), a rate typically over 100 bpm, and AV dissociation.

## **Why Each Wrong Option is Incorrect**
* **Option A:** - This option describes a feature commonly seen in VT, such as a wide QRS complex.
* **Option B:** - This option might describe another characteristic of VT, such as AV dissociation or a rapid heart rate.
* **Option C:** - This option could represent a feature like QRS complexes that are not uniform, which can be seen in VT.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that VT often presents with hemodynamic instability, including symptoms like palpitations, shortness of breath, chest pain, and potentially leading to cardiac arrest. A classic electrocardiographic feature of VT is the presence of AV dissociation, where there is no association between atrial and ventricular contractions.

## **Correct Answer:** .
