Sinus arrhythmia is a normal variation in heart rate where the pulse rate increases with inspiration and decreases with expiration. It is common in children and young adults and is usually benign, reflecting normal autonomic nervous system activity. Nurses should recognize this pattern to avoid misinterpreting it as an abnormal finding, though it may be more pronounced in certain cardiac or respiratory conditions.
