Managing Atrial Fibrillation With Lanoxin

Using Lanoxin for Atrial Fibrillation

Atrial fibrillation, the most common type of abnormal heart rhythm (or arrhythmia), occurs when the electrical system that controls the heartbeat is no longer working properly. It is sometimes called "afib" for short. Afib occurs in the two upper heart chambers (the atria). During afib, these upper chambers beat at a fast and irregular rate, out of rhythm with the two lower heart chambers (the ventricles).
Atrial fibrillation can occur occasionally or be chronic. Occasional afib means that episodes come and go. In chronic afib, the heart rhythm is always abnormal.
The actual symptoms of atrial fibrillation can vary from person to person. Some people with afib will have no symptoms at all. When symptoms do occur, they may include:
  • Feelings of a racing or pounding heart (heart palpitations)
  • Feeling like your heart is fluttering
  • Dizziness or lightheadedness
  • Shortness of breath.
(Click Symptoms of Atrial Fibrillation for more information.)
Afib itself isn't life-threatening. However, untreated afib can cause serious complications, such as:

While atrial fibrillation is rarely cured, it can often be managed with proper treatment. The type of atrial fibrillation treatment your healthcare provider recommends will depend on a variety of factors, including:
  • How long you have had afib
  • Whether your afib occurs occasionally or is chronic
  • The severity of your symptoms
  • The underlying cause.
Treatment may consist of medication (a single drug or a combination of drugs), lifestyle and dietary changes, or procedures to reset the rhythm of the heart (electrical cardioversion). The goals of treatment often include:
  • Returning the heartbeat to a normal rhythm
  • Controlling the heart rate
  • Preventing the formation of unwanted blood clots
  • Treating any underlying health problems.
Lanoxin is indicated to treat chronic atrial fibrillation by slowing down and controlling the heart rate. It does not cure atrial fibrillation or stop afib from occurring.
