AFib with RVR treatment

What exactly is AFib?

The most common form of arrhythmia in adults is atrial fibrillation, or AFib.

When the heartbeat has an irregular rate or rhythm, it is called a heart arrhythmia. This could indicate that it beats too slowly, too fast, or irregularly.

Arrhythmias are frequently asymptomatic and do not result in symptoms or complications. Some styles, on the other hand, may have severe implications and necessitate treatment. Heart failure, heart attack, stroke, or poor blood flow that causes organ damage may all be caused by dangerous arrhythmias. The majority of people with arrhythmias, including those who need care, lead regular, safe lives.

RVR (rapid ventricular rate or response) accounts for around 2% of all heartbeats. AFib can be sporadic or permanent in people under the age of 65, according to a reliable source. The incidence increases to around 9% in people over the age of 65.

AFib is caused by irregular electrical impulses in the upper chambers of the heart, the atria. These chambers quiver or fibrillate rapidly. As a consequence, blood is pumped through the heart at a fast and erratic pace.

The fibrillation of the atria causes the ventricles, or lower chambers of the heart, to beat too quickly in some cases of AFib. A fast ventricular rate or reaction is what this is known as (RVR). You’ll notice signs if you have AFib with RVR, such as a fast or fluttering pulse. Chest pain, shortness of breath, dizziness, and passing out are all possible symptoms. Your doctor will detect RVR and confirm it. It may lead to severe problems and necessitates medical attention.

Dangers of RVR

When the ventricles beat too fast, blood from the atria does not fill them full. As a result, they are unable to effectively pump blood out to satisfy the body’s needs. This will eventually result in heart failure.

People who already have some form of heart disease are more likely to develop heart failure as a result of AFib with RVR. RVR can worsen conditions like congestive heart failure by causing chest pain.

AFib without RVR

AFib may occur without the presence of RVR. You may not have any symptoms if you have AFib but a typical ventricular response. If you have AFib without RVR, you can experience some symptoms. Shortness of breath, dizziness, exhaustion, and heavy sweating are examples of these symptoms.

Using RVR to diagnose AFib

An electrocardiogram is the only way to determine whether or not you have AFib or RVR (EKG). This is a monitoring instrument that tracks the heart’s electrical activity. On an EKG, AFib and RVR produce distinct patterns of electrical waves that doctors may use to confirm the arrhythmia’s existence.

An EKG can be done in a doctor’s office, but a Holter monitor can also be used to record the heart for 24 hours. This provides a more complete picture of the heart’s activity. Heart monitors can also be worn for longer periods of time.

Treating AFib with RVR

Some people with AFib don’t need to have their arrhythmia treated. The arrhythmia is made more severe by the existence of RVR or other health conditions. Care is needed in these situations.

There are three goals of treating AFib with RVR:

  • The RVR is under your control.
  • Reduce the chances of getting a blood clot.
  • Control your AFib symptoms.

Medications are usually the first line of defense against ventricular rate control. The following are some of the most common drugs used to slow the ventricular rate in people with this condition:

  • Propranolol and other beta-blockers
  • Diltiazem, for example, is a calcium channel blocker.
  • Digoxin is a type of antibiotic that is used to

Medication may not be able to restore a normal ventricular rate in certain patients. An artificial pacemaker may be implanted in this situation. The heart’s beating is regulated by this electronic device. Ablation is a possible alternative. This is a specialist-performed operation that removes the irregular electrical pathway that is triggering the arrhythmia.


Most people with AFib, including those with RVR, will live a normal life. Maintaining healthy blood and oxygen supply to the heart, brain, and body necessitates controlling the heart rate.

RVR treatment for AFib is normally successful, but the condition can recur. To learn more about the prognosis for your particular condition, speak with your doctor.
