Pulse is an important indicator of human activity. Its normal level suggests that the functions of the body work without interruption. Deviations when listening to the pulse are alarming and make you think about what is wrong with health.
To know exactly whether to worry, you need to be aware of the limits of the norm. In adults, it is one, and the rate of pulse in children is completely different. If any deviations in rhythm are determined by an adult, they can be attributed to age-related changes. In children, the wrong pulse arises for a reason and can serve as the first bell about serious pathologies in the body.
What is a pulse?
Pulse is the oscillations of the walls of blood vessels, resembling tremors or shocks. Since the vessels are different, the pulse in them is called differently. It happens capillary – oscillations of the walls of small vessels, that is, capillaries. There is also a venous and arterial – here we are talking about larger vessels. Usually, arterial pulses are measured to assess the condition, most often in the area of the radial artery (wrist) or the carotid artery located on the neck.
Evaluate the normal value of several components:
- Frequency. This is the number of arterial oscillations per minute. It is rare, moderate and frequent.
- Filling. It is measured at the peak of impact, which characterizes the amount of blood in the vessel. By filling the pulse is moderate (normal), full (above the norm), empty (hard to hear) and threadlike (almost disappearing).
- Rhythm. Determined by the intervals between beats. If they are the same – the pulse is rhythmic, if not – arrhythmic.
- Voltage. Estimated by the force applied when clamping the arteries for listening. Distinguish moderate, hard and soft pulse.
Also taken into account is the form, or pulse rate and its height. By evaluating all these parameters, it is possible to know if there are any deviations.
Norm for a child
The initial examination to identify pathological conditions begins with the measurement of heart rate (HR). This value depends directly on the size of the human heart. The larger the heart, the less heartbeat it needs for pumping blood. Accordingly, in young children this indicator is frequent, since their heart muscle needs to be reduced much more times than the heart of an adult. Also, this factor can be influenced by such nuances as: heat / cold, body temperature, current diseases, the child’s endurance level and even an emotional state. Below are the approximate boundaries of the normal pulse rate for children of different age groups (+/- 30 beats / min):
- 140 beats. / min – newborns up to 1 month.
- 135 beats. / min – from 1 month to 1 year.
- 125 beats. / min – from one to two years.
- 115 beats. / min – from 2 years to 4.
- 105 beats. / min – 4-6 years.
- 100 beats. / min – from 6 to 8 years.
- 90 beats. / min – from 8 to 10 years.
- 80 beats. / min – up to 12 years.
- 75 beats. / min – up to 14 years.
After 14-15 years, the pulse stops slowing as the heart reaches adult size.
Now the average frequency is 70 beats per minute, and the possible deviations in one direction or the other does not exceed 20 beats.
Bradycardia and tachycardia
Both slow and too fast pulse indicates the state of the child’s heart system. If the heart rate below the age norm by more than 30 beats, we can talk about bradycardia. Normally, if the heart beats slower in children involved in sports. But when bradycardia is diagnosed simultaneously with other symptoms (weakness, pallor, dizziness and hypotension), this is serious and requires immediate medical advice.
Acceleration of heart rate is called tachycardia. Against a background of stress, cold or physical activity, this is normal. However, tachycardia can also be a sign of heart and endocrine disorders, severe fatigue, anemia, or breathing problems. To establish the cause, the doctor will recommend an ECG, ultrasound, phlebogram, sphygmogram, and other necessary studies. It is important for parents to be well-versed in this matter so as not to miss the time to go to the hospital.
In children’s educational institutions, at the beginning of each year, children are given a sample of Rufe.
This measurement of the heart rate in a special way with the derivation of the coefficient by which the permissible physical load for each child is determined individually. Do not neglect such at first sight insignificant examinations. Only vigilance will not allow your child to replenish the figures of the sad statistics of heart disease.
