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.
What the difference between tachycardia and a-flutter? Both are "regular" irregular heart beats where the heart is beating way too fast (vs. a-fib which is an "irregular" irregular heartbeat). Do they come from different causes? Are they treated differently?
