Is it dangerous if a bradycardia in a child is detected
Bradycardia in a child affects the quality of life of his and his parents, prevents the baby from developing normally and communicating with other children. Observation with a cardiologist is necessary. A timely disease not detected, if it is in serious form, is fraught with a fatal outcome.
Symptoms and causes of the disease
Bradycardia is characterized by a decreased heart rate. Throughout life, the number of beats per minute varies. For babies, the normal frequency of reduction is 100-140 beats per minute, after a year the rhythm of the heart changes, and it is normal to take 120 strokes per minute. By the age of 3, normal heartbeats are about 115 beats per minute, and in adolescence no more than 100. There are individual features of the heart rhythm, depending on the constitution, weight and child temperament.
Most often, the bradycardia of a child occurs in connection with the pathology of the myocardium, because of which the tone of the vagus nerve is significantly increased. In most cases, the impulse is impaired in this disease by a sinus node - this kind of disease is called sinus bradycardia.
There is another type of disease - heterotropic, in which the conductive system of the myocardium is disturbed. In children, it is rare.
Moderate bradycardia in children can be both congenital and acquired. It can occur for a short period in the cold season, with long walks. Heart rhythm with this form of the disease slows down on exhalation.
The disease may appear :
- during the disturbance of cerebral circulation in infants and in the intrauterine period in the presence of hypoxia;
- because of congenital heart disease;
- with diseases of the nervous system and severe hypothermia;
- as an allergic reaction to intoxication when using drugs or substances that affect the activity of the cardiovascular system;
- as a consequence of the transmitted infections.
Bradycardia in a child in adolescence is sometimes found during intense growth. Adolescents are prone to neuroses, mood swings, restructuring of the endocrine system does not always keep up with the increase in internal organs. Violated in the body metabolic processes, and the consequence is a slowing of the heart rate.
- fast fatiguability;
- inability to concentrate attention;
- frequent syncope;
- with short physical effort;
- poor appetite, general lethargy;
- pressure jumps;
- the sternum may have periodic pain.
Treatment of bradycardia
If bradycardia is detected in a child, then initially it is necessary to determine its cause and stage of the disease. Drug therapy in each case is selected individually.
Congenital bradycardia, if surgery is not required, is most often corrected by substances normalizing oxygen exchange.
As special periods of the organism's reorganization, the preschooler allocates time from 3 to 5 years. This period is the first period of active development of the cardiovascular and respiratory systems. Bradycardia in a child of 3 years can arise due to the formation of deep breathing. A similar manifestation of the disease is considered physiological and does not require drug therapy. It is enough to create comfortable conditions for the child and relieve nervous tension.
The same advice can be given in the treatment of symptomatic bradycardia in adolescents. Most often, no treatment is required, the child outgrows himself. If, within 2 years, the body has not recovered from hormonal adjustment, then treatment is required from the cardiologist.
