A heart rate of 127 beats/minute may be a physiologic normal heart rate or an abnormal heart rate due to disease.
Generally the younger the child, the faster the heart rate, mainly related to pediatric metabolism and high sympathetic excitability, such as newborns 120 ~ 140 beats / min, < 1 year old for 110 ~ 130 beats / min, heart rate of 127 beats / min in these age groups is a normal performance.
After strenuous exercise, mental stress, excessive alcohol consumption will lead to a significant increase in heart rate, up to 127 beats per minute/minute is also normal, after the removal of various external stimuli, the heart rate will return to normal.
The normal heart rate of 1 to 3 years old is 100 to 120 beats/min, 4 to 7 years old is 80 to 100 beats/min, 8 to 14 years old is 70 to 100 beats/min, and the normal heart rate of adult is 60 to 100 beats/min. 127 beats/min should be considered as a result of disease after physiological reasons are excluded.
The heart rate of 127 beats/min measured in quiet or resting state in the above age group belongs to tachycardia, which may be caused by sinus tachycardia, atrial fibrillation, ventricular tachycardia, anemia, and hyperthyroidism.
If the heart rate is 127 beats/minute and accompanied by other discomforts, consult a doctor promptly.
