While reading an EKG, you note an absence of P waves and the presence of flutter waves at a rate of 250-350 pm. What type of EKG is this?
  1. Beta flutter
  2. Atrial flutter
  3. Atrial fibrillation
  4. Junctional rhythm
Explanation
Answer - B - An EKG that has an absence of P waves and the presence of flutter waves at a rate of 250-350 pm is displaying atrial flutter. Atrial flutter results from a rapid atrial reentry circuit and an AV node that cannot handle all impulses through to the ventricles. The flutter waves resemble a saw-tooth or picket fence pattern.
