Is AFib With RVR Life-Threatening?
AFib with RVR can be life-threatening. Patients who have AFib have a 1.5- to 1.9-fold higher risk of death, due to the increased risk of blood clots (thromboembolism) and stroke.

AFib with RVR (atrial fibrillation with a rapid ventricular rate) can be life-threatening. Patients who have AFib have a 1.5- to 1.9-fold higher risk of death, due to the increased risk of blood clots (thromboembolism) and stroke.

AFib (atrial fibrillation) is an irregular or abnormal heartbeat (arrhythmia). In A-fib, the upper chambers of the heart (the atria) beat irregularly because the electrical signals that control the heart are not functioning properly. As a result, blood is not moved out of the upper chambers as fast as it should be and blood clots may form. Blood clots increase the risk of stroke

AFib with RVR is atrial fibrillation with a rapid ventricular rate. This means the lower chambers of the heart, the ventricles, beat too fast.

What Are Symptoms of AFib With RVR?

Atrial fibrillation may not always cause symptoms. 

Mild symptoms of atrial fibrillation may include:

Severe symptoms of atrial fibrillation may include:

What Causes AFib With RVR?

AFib with RVR (atrial fibrillation with a rapid ventricular rate) is caused by faulty electrical signals in the heart.

Risk factors for developing AFib with RVR include age and underlying heart diseases. The most common causes of AFib include heart conditions such as:

Other risk factors for developing AFib with RVR include:

How Is AFib With RVR Diagnosed?

AFib with RVR (atrial fibrillation with a rapid ventricular rate) is diagnosed with an electrocardiogram (ECG or EKG), a test that measures the heart's electrical activity. 

A Holter or event recorder (devices worn over 1-2 days that monitor heart activity using an ECG recording) may be used in some cases. 

Tests that may be indicated to check for other problems include:

  • Echocardiogram (ultrasound) to check for heart failure or heart valve problems
  • Sleep studies to check for sleep apnea
  • Lung function tests to look for underlying lung disease
  • Blood tests to screen for thyroid disorders

What Is the Treatment for AFib With RVR?

The goal of treatment for AFib with RVR (atrial fibrillation with a rapid ventricular rate) is to control heart rhythm and rate and to stop blood clots from forming (anticoagulation) to prevent stroke

Treatment to control heart rhythm includes:

Treatment to control heart rate includes:

  • Medications
  • Placement of a permanent pacemaker (used when other rate and rhythm control alternatives have not been successful)

Anticoagulation treatments include:
