What Is AFib with RVR?

Q: On the report of my mother’s diagnosis of atrial fibrillation, I noticed the words “AFib with RAR”. I know that AFib is the abbreviation of atrial fibrillation, but I don’t know what RAR is. What does RAR refer to?

A: RAR refers to rapid ventricular rate or response. It means that the rate or response of the lower chambers of the heart is too fast. And “AFib with RAR” is atrial fibrillation with rapid ventricular rate or response.

AFib is caused by abnormal electrical impulses in the atria (the upper chambers of the heart). In some cases, the fibrillation of the atria causes the ventricles to beat too fast. Thus the patient develops AFib with RVR. Patients having AFib with RVR experience symptoms, typically a rapid or fluttering heartbeat.

There are three goals of treating AFib with RVR. They are controlling the RVR, reducing the risk of blood clots and controling the symptoms of AFib. Common medications used to slow the ventricular rate in people with this condition include beta-blockers such as propranolol, calcium channel blockers such as diltiazem and digoxin.
