atrial fibrillationIrregular rhythm (arrhythmia) of contraction of the atria (upper heart chambers). The most common major arrhythmia, it may result as a consequence of increased fibrous tissue in the aging heart, of heart disease, or in association with severe infection. If it continues, it can permit formation of blood clots, which can block blood flow to essential organs. Emergency treatment consists of drugs such as beta-blockers or digitalis, which slow the heart's action, and anticoagulants. In addition, atrial fibrillation can be interrupted by administering electric shocks (defibrillation). See also ventricular fibrillation. |

This feature is especially valuable in
diagnosing Afib as often times patients don't feel symptoms during
an Afib episode. Triggered by rapidly firing stimuli or premature beats arising from
within the pulmonary veins, AFib is the most common cardiac arrhythmia
affecting approximately 2. Most AFib patients are treated
with blood thinners, which unfortunately put patients at risk of serious
bleeding if they fall or bruise themselves. |
