Atrial Fibrillation ECG

All of the following ECGs reveal irregular rhythms due to atrial fibrillation. While looking at an ECG of atrial fibrillation, one of the first things that you might notice is that there aren’t any P waves. Instead, there is a quivering baseline with interspersed QRS complexes. These atrial undulations are the result of rapid and erratic atrial depolarization and are referred to as fibrillatory waves. These fibrillatory waves can be either fine (i.e., less than 1 mm in amplitude) or coarse (i.e., greater than 1 mm in amplitude). When they are fine and have a low amplitude, they can appear as a smooth, wavy line or even a flat isoelectric line. These fibrillatory waves occur without any association to the irregularly dispersed QRS complexes.
