ECG Question #27


A nurse caring for a client in the Intensive Care Unit observes the cardiac monitor and notes a rate of 165 bpm, no P waves, and wide QRS complexes. The nurse determines the client’s rhythm is:


  1. Premature ventricular contractions
    • Rationale:
  2. Ventricular tachycardia
    • Rationale:
  3. Sinus tachycardia
    • Rationale:
  4. Atrial Tachycardia
    • Rationale:



Ventricular tachycardia (V-Tach) is characterized by absent P waves, wide QRS complexes and a rate between 100 and 250 impulses per minute. The rhythm is usually regular. The characteristics of the client’s rhythm do not indicate premature ventricular contractions, sinus tachycardia, or atrial tachycardia.
