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.
Just curious - with the new anticoagulants - since there's no routine blood testing, how do they know where your INR is? How do you know it's not too high? Do they wait for a bleed to happen?
