Final answer:

In a patient with sinus arrhythmia, the presence of multiple P waves indicates a difference as it is characteristic of this condition along with an irregular pulse rate within normal limits.


Explanation:

Answer:

In a patient with sinus arrhythmia, multiple P waves would be different. Sinus arrhythmia is characterized by irregularity in the beat originating from the sinoatrial (SA) node, resulting in variations in the P-wave morphology but with a normal QRS complex. This condition is marked by an irregular heart rate within normal limits (60-100 beats per minute).

Moreover, if a patient with sinus arrhythmia had an absent or abnormally shaped QRS complex, it would indicate another underlying issue beyond sinus arrhythmia.
