EKG Drill Answer

This is Atrial Fibrillation. Look for rhythm that is irregular, with heart rate that is very fast (> 350 bpm) for atrial, but ventricular rate may be slow, normal or fast. Notice that the P wave is absent - erratic waves are present. The PR interval is absent. The QRS is typically normal but may be widened if there are conduction delays.
