PSG Boards Exam Prep What is Atrial Fibrillation? - In atrial fibrillation, the electrical activity of the heart is uncoordinated, with electricity traveling about the upper chambers in a chaotic fashion, causing the upper chambers to quiver (like a "bag of worms") and contract inefficiently or not at all. Common in elderly and those with heart disease. What is Atrial Flutter? - Atrial flutter causes a rapid but coordinated electrical stimulation of the upper chamber of the heart, of...
