Symptoms

Bradycardia in children is manifested by a decrease in the number of heartbeats. Often pathologies are accompanied by diseases that triggered the development of bradycardia. In this case, therapy is required, it is determined by the cardiologist. Independent treatment is strictly prohibited, as it can cause complications and worsen a child's condition.

Classification

What is bradycardia in children, it is quite easy to understand if the norms of reduction are known:

  • Bradycardia in newborns and children under 1 year of age - the heart rate is 120 beats per minute.
  • From two to three years - 110 beats per minute.
  • In children from 5 years to 6 years - the norm of 90-100 beats per minute.
  • From 7 years to 9 years - 85 - 95 strokes.
  • In 10 years (from 9 to 12 years) - not less than 80 strokes.
  • In adolescents, bradycardia is diagnosed if the number of strokes is less than 70.

After the ECG, a form of pathology is revealed:

  • Heterotopic - gets development if the activity of the sinus node is reduced and the conductor is another part of the cardiac muscle. The heterotopic form is rare.
  • Sinus - in such situations conductivity of impulses without pathologies and they pass in the necessary directions, the tone of the vagus nerve increases. This also provokes a rhythm disturbance.
  • Blockade of the heart - bradycardia of the heart in children in this form is diagnosed when a number of sent impulses do not reach the ventricles, which causes a reduced number of cuts, which is 35-40 strokes per minute. A distinctive feature of this form are syncope and convulsions.

There are several degrees of the disease:

  • Easy - the number of cuts varies from fifty to sixty beats per minute.
  • Moderate - 40-50 strokes.
  • Expressed - the maximum number of cuts reaches 40 beats per minute.

The first two degrees are not considered dangerous if there are no other cardiac pathologies. Most often, after a while, the rhythm is restored independently.

In the opposite case, treatment is necessary, because of a lack of oxygen, there are violations in the vessels, especially in the arteries that feed the brain.

.

Attention! Scientists have proved that the life-time depends on the frequency of the heart rhythm. The lowest number of abbreviations within the norm contributes to longevity.

Causes

A number of causes are identified that become the culprits of the disease in childhood:

  • Violation of electrolyte balance, which is formed when there is insufficient quantity of electrolytes in food.
  • Regular sports activities contribute to the development of moderate bradycardia.
  • Pathologies of an infectious nature.
  • Congenital malformations of the heart muscle.
  • Myocarditis.
  • Severe hypothermia of the body.
  • Uncontrolled use of drugs.
  • Neuroses of a different nature.
  • Intoxication of the body with nicotine.
  • Kawasaki disease is a rare immunocomplex inflammatory lesion of the arteries.
  • Accelerated growth of the body (the heart, among others) in adolescents.
  • Neurocirculatory dystonia (NDC).
  • Pathologies of the thyroid gland.
  • Violation of hormonal levels in adolescents.
  • Defects of blood circulation in the brain.
  • Intoxication with lead.
  • Oxygen starvation.
  • Edema of the brain, caused by diseases of the nervous system.
  • Insufficient level of hormones (hypothyroidism).

Sometimes symptoms can arise due to severe fright or prolonged respiratory arrest. However, in this case, treatment is not required, since everything passes by itself.

The risk of the disease is as follows:

  1. Insufficient level of oxygen that enters the brain.
  2. Oxygen starvation of all organs and systems.
  3. Due to the heavy burden on the heart (it is necessary to throw out more blood for one reduction), it increases, and the myocardium becomes thinner.
.

Important! In the infant, a bradycardia is observed more often due to the fact that in the womb of the mother the fetus developed certain cardiac pathologies, or as a result of hypoxia of the fetus.

Bradycardia in the newborn

Symptoms

Bradycardia in children is manifested as follows:

  • General malaise, lethargy.
  • Dizziness.
  • Decreased appetite.
  • Complication of breathing, the occurrence of dyspnea.
  • Intensive work of sweat glands.
  • Pale skin.
  • Fainting.
  • Frequent pressure changes.
  • Inattention.
  • Memory impairment.
  • Decreased concentration of attention.
  • Rapid fatigue even with low physical exertion.
  • Pain in the heart.
  • Slow pulse.

All these symptoms indicate a violation of the heart, often there is a gradual death of cells, which leads to a thinning of the heart muscle. Over time, in the absence of treatment, it does not stand up and a break occurs. In the end, inevitable death.

An easy degree of disease has only one symptom - a reduced number of heartbeats. In more severe cases, fainting is accompanied by convulsions, stopping breathing, and involuntary urination and defecation are often observed. And the heart at this time is not reduced.

Treatment

Bradycardia in a child requires constant monitoring by a cardiologist, and in more mild cases, treatment is not required. Here you can use the methods of traditional medicine, but in advance you need a consultation with a specialist. You can make decoctions of yarrow, needles, give your child strong tea, walnuts and seaweed. In the mornings do sports exercises, provide long walks in the fresh air. It is treated at home.

In more severe cases, it is necessary to undergo a course of antiarrhythmic drugs. Most often the doctor appoints the following:

  • Atropine.
  • Isadrin.
  • Caffeine.
  • Ephedrine.
  • Euphyllinum.
  • Extracts of eleutherococcus, belladonna, belladonna, ginseng.

Selection of treatment goes individually for each child, and the initial therapy is sent to eliminate the cause. To achieve a sustainable result, all the recommendations of the attending physician should be followed. The course of therapy must pass to the end, even if all the signs have disappeared before.
