Ventricular tachycardia is

• A. A normal sinus rhythm with fast rate
• B. Ventricular fibrillation pattern
• C. A supraventricular tachycardia
• D. An accelerated idioventricular rhythm with a higher rate

Answer: (D)

Ventricular tachycardia is a rapid heart rhythm that originates in the ventricles, not from the atrial pacemaker. It typically presents as a fast rate with wide QRS complexes and can be sustained and dangerous, possibly causing hemodynamic instability. Among the choices, the description that conveys a ventricular rhythm with an elevated rate best fits VT, since it emphasizes both the ventricular origin and the fast rate. The other options describe a normal sinus rhythm with speed, a chaotic erratic pattern of ventricular fibrillation, or a rhythm arising above the ventricles (supraventricular tachycardia) with usually a narrower QRS. Accelerated idioventricular rhythm is a ventricular rhythm that is generally slower, but when described as a higher rate it points to a fast ventricular rhythm, aligning with the concept of VT in this context.
