Accelerated Idioventricular Rhythm features?

Accelerated Idioventricular Rhythm features?

• A. Rate 25-40 bpm
• B. Rate 50-100 bpm with three or more consecutive ventricular beats
• C. Rate >100 bpm with tachycardia
• D. Rate 40-60 bpm

Answer: (B)

Accelerated idioventricular rhythm is a ventricular rhythm that sits between a slow escape rhythm and true ventricular tachycardia. The defining features are that the rhythm originates in the ventricles, the rate falls in the ventricular range (roughly 40–100 beats per minute), and there is a run of three or more consecutive ventricular beats. This combination distinguishes it from slower ventricular escape rhythms and from ventricular tachycardia, which is typically faster than 100 bpm. The best description among common choices is a rate around 50–100 bpm with three or more consecutive ventricular beats. If the rate is above 100, it would be ventricular tachycardia; if it’s only 25–40, that’s a slower ventricular escape rhythm; and simply listing 40–60 bpm without noting the consecutive ventricular complexes wouldn’t fully define AIVR.
