Which rhythm has a ventricular rate greater than 100 bpm?

Explanation:
Understanding how ventricular rhythms are categorized by rate helps you pick the one that exceeds 100 bpm. Idioventricular rhythm is slow, typically around 20–40 bpm. Accelerated idioventricular rhythm is faster but usually maxes out around 100 bpm and is not considered a true tachycardia. Junctional escape rhythm stems from the AV junction and runs about 40–60 bpm. Ventricular tachycardia, however, is a rapid rhythm coming from the ventricles and has a ventricular rate greater than 100 bpm (often with a wide QRS). Because the question specifies a ventricular rate over 100 bpm, ventricular tachycardia is the correct fit.
