The ECG shows regular P waves and regular QRS complexes, but the P waves have no consistent relationship to the QRS complexes. The ventricular rate is 36 beats per minute. Which rhythm is most likely present?
Correct answer: A. Complete heart block
- A. Complete heart block
- B. First-degree heart block
- C. Sinus bradycardia
- D. Atrial fibrillation
Explanation
Complete heart block causes atrioventricular dissociation, so the atria and ventricles beat independently. First-degree block has a prolonged but constant PR interval, sinus bradycardia keeps P waves linked to QRS complexes, and atrial fibrillation lacks regular P waves.
