In terms of rhythm regularity, how is ventricular tachycardia classified?

Ventricular tachycardia (VT) is classified as having a regular rhythm because it typically presents with consistent intervals between QRS complexes. This regularity occurs because VT arises from a rapid series of impulses originating in the ventricles, resulting in a stable and predictable pattern of heartbeats that occur at a fast rate, often between 100 and 250 beats per minute.

The absence of varying timing between contractions distinguishes it from other types of dysrhythmias, such as atrial fibrillation or irregular ventricular rhythms, where QRS complexes occur at varying intervals. Recognizing the regularity of VT is crucial for proper diagnosis and treatment, as it indicates a sustained arrhythmia that may require immediate medical intervention.
