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

A. First degree AV heart block: The rhythm is regular, P waves are present and consistent, and each P wave is followed by a QRS. The defining feature is the consistently prolonged PR interval (greater than 0.20 seconds), which indicates a delay in conduction through the AV node. B. Junctional escape rhythm: A junctional escape rhythm originates in the AV node, typically has a slower rate (40-60 bpm), and P waves are either absent, inverted, or occur after the QRS complex. This strip has P waves preceding each QRS and a normal rate. C. Sinus bradycardia: Sinus bradycardia has a heart rate less than 60 bpm. This strip shows a rate of approximately 75 bpm. D. Normal sinus rhythm: While many parameters (rate, regularity, P wave presence, QRS width) might suggest a sinus rhythm, a normal sinus rhythm requires a PR interval within the normal range (0.12-0.20 seconds). This strip has a prolonged PR interval.
