Atrial fibrillation with rapid ventricular response is a fancy name for an irregular heartbeat. When your heart's electrical signals aren't working right, it can lead to a heartbeat that's too fast.

Afib can send many electrical signals to the bottom heart chambers (known as the ventricles) and can trigger RVR (rapid ventricular response), which can cause rapid heart rates. If a heart beats ...

In AFib with rapid ventricular response, the atria (upper chambers ... between the atria and ventricles of the heart and can cause a fast heart rate. Cardioversion may be part of managing AFib ...

From its triggers to its symptoms, atrial fibrillation, or afib, can be unpredictable. Afib is a type of heart rhythm disorder that starts in the upper chambers of your heart, known as the atria.

From there, the signals travel to the lower chambers of your heart. The basic cause of AFib is disorganized signals that cause the atria of your heart to squeeze very fast and out of sync.

When AFib-RVR occurs, symptoms are often burdensome enough to cause patients to seek acute care in the emergency department, where standard-of-care procedures include intravenous administration of ...
