The nurse is reviewing an electrocardiogram ECG) rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64 beats/minute. What is the correct interpretation based on these characteristics?

Question

Quizplus · Accepted Answer

The electrocardiogram (ECG) characteristics describe a normal sinus rhythm with a heart rate of 64 beats/minute. The PR interval is within normal limits at 0.12-0.20 seconds, and the QRS complex duration is narrow at less than 0.12 seconds. There are no abnormalities present that would suggest sick sinus syndrome, sinus bradycardia, or first-degree heart block.
