ECG Question #7


A client in the ICU received advanced cardiac life support after his monitor revealed the following rhythm, which the nurse identified as:


  1. Supraventricular tachycardia
    • Rationale:
  2. Complete heart block
    • Rationale:
  3. Ventricular fibrillation
    • Rationale:
  4. Ventricular tachycardia
    • Rationale:



Ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles. In this rhythm atrial activity is absent. Supraventricular tachycardia has discernable QRS complexes. In complete heart block, the atrial rhythm is different from the ventricular rhythm. In ventricular tachycardia, three or more premature ventricular contractions occur in a row with a heart rate that exceeds 100 bpm. The ventricular and atrial rhythms are usually regular however the P wave may be difficult to detect.
