Ventricular Tachycardia is best described as?

• A. A slow heart rhythm.
• B. A rhythm originating in the atria.
• C. A rhythm produced by pacing devices.
• D. A fast rhythm originating from the ventricles.

Answer: (D)

Ventricular Tachycardia is a fast heart rhythm that starts in the ventricles. The crucial point is the origin of the electrical impulse: VT arises from the lower chambers, not the atria, and “tachycardia” signals a rapid rate. On ECG, this usually appears as wide QRS complexes with a regular, rapid rhythm, typically around 120–250 beats per minute. This combination distinguishes it from slower rhythms and from rhythms that originate in the atria (like atrial tachycardia or supraventricular tachycardia). It’s also not due to pacing devices, which can produce a rhythm but are not the intrinsic VT pattern. Recognizing VT is important because the rapid ventricular rate can compromise cardiac output and often requires urgent assessment and management.
