Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.
The therapeutic range for digoxin has been established over time as 0.5-2.0 ng/ml for those being treated for heart failure. Several new studies suggest a more narrow range, 0.5-1.0 ng/ml, may be appropriate for some people. The recommended range for someone with arrhythmia is 1.5-2.0 ng/ml. Most people find that their symptoms improve when their digoxin levels are within these ranges.
