Solution Steps

Step 1: Analyze the P waves

Each QRS complex is preceded by a P wave that is upright in lead II. This suggests a sinus origin for the rhythm.

Step 2: Evaluate the QRS complexes

The QRS complexes are narrow, indicating that the ventricular activation is proceeding normally.

Step 3: Assess the rhythm

The rhythm appears regular, and the P-P and R-R intervals are relatively constant. The rate is within the normal range for a sinus rhythm.

Final Answer

NSR
