Pulse: rate in children, by age table

Heart rate is an important physiological indicator, which displays the status of the cardiovascular system. Normal values in adults and children differ. In this article we will discuss what should be the pulse of the child.

The pulse is palpable hand vibrations of the walls of arteries that occur in response to the ejection of blood by the heart. The rules for determining this index in children:

  • The most accurate heart rate information you can get in the morning, while the child is still not eating and is calm, since emotional arousal, and any physical exertion and even eating affect the heart rate and pulse rate. These two parameters are interrelated and differ from each other only in pathological conditions, when after the reduction of the heart pulse wave does not apply to vessels.
  • During the measurement the patient should either sit or lie down. In the standing position, the heartbeat is always a little learning.
  • After active movements, crying and emotional outbursts must be at least 10 minutes, the heartbeat was restored, and the resulting figure was the objective.
  • To determine the pulse preferably alternately on two hands in the wrist joint by probing (on the inner surface of the hand from the thumb). Young children can be used for measurements on the carotid and temporal arteries.
  • Consider the aftershocks of the artery doctors recommend 30 or 60 seconds (when measuring in 30 seconds the resulting value must be multiplied by 2).

The norm for ages

Newborns pulse much more often than adults. Every year of life the frequency of the heart’s contractions getting closer to the adult norm. This is more clearly displays the table for age:

For children as for adults, it is desirable that the pulse had an average value. When the heartbeat for a long period of time is the upper limit of normal, increasing the load on the heart, vessels and the entire body.

The pulse characteristics

Frequency is the most important characteristic of the pulse, which must be able to identify each person. However, there are other characteristics of this physiological parameter, they are always appreciated by the doctors. So, the normal heart rate in children should be rhythmic, normal stress, filling and value.

Here it is also worth mentioning about this concept as respiratory arrhythmia. Among children age 2 – 11 years, this physiological phenomenon is quite common. Its essence lies in the fact that the breath, the heartbeat quickens, on the exhale it becomes more rare. To exclude pathological arrhythmia, the doctor asks the patient to stop breathing during the evaluation of pulses, auscultation of the heart or an EKG.

The heart rate during sleep: what is normal?

Parents of young children are often concerned about the question, is it normal when the baby is sleeping, his heart beats slower. From a physiological point of view, the decrease of pulse rate during sleep is considered quite normal for children of the first year to 80, for older children – up to 50 – 60 per minute.

Permissible variations of the pulse in a child

The frequency of pulsation of the arteries is influenced by various factors both physiological and pathological. Allowable physiological deviation of the heart rate – 10% from the norm in one direction or another. If the heartbeat more often or Vice versa less often than expected, you should understand the causes of this phenomenon. Affect the heart rate following physiological factors:

  • Sex. The girls heart is still beating for 3 to 5 beats per minute.
  • Hormones. Puberty almost always accompanied by an increase in heart rate on average 10 to 12 beats per minute, when compared with the normal rates. It happens in children of both sexes.
  • Fear, severe anxiety, prolonged crying, physical stress (even intense sucking of the breast) – these factors accelerate heartbeat, increase blood pressure, speeds up breathing. However, in a healthy child all of the indicators should return to normal within 2 – 3, a maximum of 5 minutes. If it does not, you should look for another cause palpitations.

It is also worth noting that children older than 12 years involved in sports (athletics, swimming, Cycling, football and other aerobic sports), the norm may have a pulse lower than it should be according to age, and it does not affect the health and functioning of the organism as a whole. Just have physically active children, like adult athletes, the heart is trained, so it can pump more blood per contraction and therefore can fight less frequently than normal children.

Why the heart beats faster in children?

The most frequent causes tachycardia (palpitations and heart rate, respectively) in children include the following:

  • A high body temperature.
  • Autonomic disorders.
  • The hyperthyroidism.
  • Anemia.
  • Dehydration.
  • Heart disease.

Causes rare heart rate (bradycardia) in children

Heart rate is significantly below the norm may indicate the development of a number of pathological conditions:

  • Electrolyte imbalance.
  • Some infectious diseases.
  • Hypofunction of the thyroid gland.
  • Autonomic disorders.
  • Of congenital heart disease.
  • Myocarditis.
  • Poisoning by toxic substances (nicotine, lead, drugs, etc.).
  • Brain lesions, etc.

Thus, the pulse can serve as an important diagnostic marker of various diseases. Therefore, at each visit the young patients a pediatrician evaluates this physiological parameter. Of course, to determine what happens to the person that was the cause of bradycardia or tachycardia (some kind of disease or banal excitement and fear of the white coat) only for heart rate impossible. This requires other data – inspection results, laboratory and instrumental studies.
