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.
I was on 112mcg at time of first Afib attack they were lowering it slowly so was on 100mcg with second. Now they have it down to 75mcg and allmthe blood work is good. Hoping this is all I need. Funny it is the lowest amount I have needed since started at 17.
