Atrial Fibrillation Basics

  Atrial Fibrillation: Background Atrial Fibrillation – described as a ‘chaotic electric storm’ of the sino-atrial (SA) node is a cardiac dysrhythmia which results in irregular atrial discharges between 300-600/min. The irregular, non-stop arrival of conductance to the AV node leads to uncoordinated contraction (Warning: Real Heart!) between the atria and ventricles – thus leading to decreased stroke volume and…
