Based on this strip, which is the correct interpretation of this rhythm?

A. Third-degree AV block (complete heart block) is characterized by no association between P waves and QRS complexes. The atria and ventricles beat independently, with a regular atrial rate and a regular but usually slower ventricular rate. This pattern matches the rhythm described. B. A junctional rhythm originates in the AV junction and typically shows absent or inverted P waves with a regular rhythm. It does not show complete atrioventricular dissociation. C. First-degree AV block shows a consistent but prolonged PR interval, with every P wave followed by a QRS complex. This differs from the absence of conduction seen here. D. Idioventricular rhythm originates from the ventricles and shows wide QRS complexes without organized P waves, but it does not involve independent atrial activity typical of complete heart block.
