AFIB with rapid ventricular response (RVR) is described by which statement?

AFIB with rapid ventricular response (RVR) is described by which statement?

• A. The rhythm is regularly irregular
• B. The heart rate is always below 60 bpm
• C. The heart rate is always exactly 100 bpm
• D. The heart rate goes over 100 bpm

Answer: (D)

When atrial fibrillation occurs with rapid ventricular response, the key feature is a ventricular rate that is fast. In AFib, the atria fibrillate chaotically and the AV node conducts impulses in an unpredictable manner, creating an irregularly irregular rhythm. When this ventricular rate exceeds 100 beats per minute, it’s termed rapid ventricular response. So the statement that the heart rate goes over 100 bpm best describes AFIB with RVR. The rhythm in AFib is not regularly irregular, the rate is not always below 60, and it’s not fixed at exactly 100—rates vary and are typically above 100 when RVR is present.
