68. You are assessing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and QRS complexes measure 0.06 seconds. The overall heart rate is 65 beats per minute . What will the interpretation result of cardiac rhythm be? A. First-degree heart block C. Sick sinus syndrome B. Normal sinus rhythm D. Sinus bradycardia

68. You are assessing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and QRS complexes measure 0.06 seconds. The overall heart rate is 65 beats per minute . What will the interpretation result of cardiac rhythm be? A. First-degree heart block C. Sick sinus syndrome B. Normal sinus rhythm D. Sinus bradycardia

Answer 1

The correct answer is B. Normal sinus rhythm.Explanation: In a normal sinus rhythm, the P waves and QRS complexes are regular, and the PR interval is within the normal range (0.12-0.20 seconds). The QRS duration is also within the normal range (0.06-0.10 seconds). The heart rate of 65 beats per minute is within the normal range for adults (60-100 beats per minute). Therefore, the interpretation of the cardiac rhythm in this case would be normal sinus rhythm.
