A 5 year old child with a fast heart rate during the day and normal sleep at night usually does not need treatment.
Normal adult heart rates tend to be in the range of 60-100 beats per minute. However, children’s heart rate can be faster and the range can be relaxed to about 80-110 beats. The patient is still young and in the active age group, and a faster heart rate during the day is considered to be associated with activity as well as age-related acceleration of the heart rate.
In addition, there may be physiologic or pathologic reasons for the fast heart rate. Physiologic heart rate increases can be caused by stress, lack of sleep, or the consumption of foods that increase the heart rate, such as coffee or tea. Pathological tachycardia can be seen in sinus tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia.
The patient is in childhood, except for the rapid heart rate without other uncomfortable symptoms, generally do not need treatment; but need to observe the patient’s clinical manifestations, such as chest tightness, shortness of breath, sweating, or even cyanosis, fainting and other discomforts, go to the hospital for treatment in a timely manner.
