This is Sinus Arrhythmia. Look for rhythm that is irregular, varying with respiration, with heart rate that is normal (60-100 bpm) and rate may increase during inspiration. Notice that the P wave is normal. The PR interval is normal (0.12-0.20 sec). The QRS is typically normal (0.06-0.10 sec). Heart rate frequently increases with inspiration, decreasing with expiration.
