Bradycardia in children - how dangerous it is?
bradycardia in children is not uncommon.It may be the result of congenital sinus node automaticity reduction, which is called the pacemaker.But most of bradycardia is the result of various diseases or common intoxication.In any case, if the child has severe bradycardia, should consult a doctor.
What does fetal bradycardia
bradycardia - a decrease in heart rate (HR).It can occur as early in utero.So, bradycardia embryo (the first 8 weeks of development) indicates a high risk of chromosomal abnormalities (Down's syndrome, Edwards Patoau and others).During prenatal development of the child should be carefully - very high risk of disorders of the central nervous system, heart diseases and so on.
fetal bradycardia (after 8 weeks of development) often suggests that the fetus is suffering from placental circulation disorders - it lacks nutrients and oxygen.Medical ultrasonography in this case marks the duration of bradycardia: matters only prolonged or permanent reduction in heart rate.If the heart rate after a while it becomes normal or higher than normal, it is most likely talking about the immaturity of automatism sinus and is not dangerous.Bradycardia in the fetus may also speak at the possible formation of a congenital heart defect.This fruit is also subject to close monitoring.
Causes of bradycardia in children
human heart is capable of decline under the influence of pulses that occur within it.This ability is called an automaton.It provides special muscles that form a series of nodes and beams in the heart - vascular system.It includes the sinoatrial node, atrioventricular node and branches (beams) on them, which are held to the heart muscle nerve impulses.
Bradycardia can be of two types - sinus and because of the blockade of impulses between the sinoatrial node and the atria or between the atria and ventricles.
Sinus bradycardia in infants may be due to congenital reducing sinus automaticity - pacemaker.Pathological sinus tachycardia Tachycardia - the body to the limit? may be due to birth trauma Birth injuries - than they threaten your child? and compression of the vagus nerve.
Sinus bradycardia in children, which is not accompanied by any impairment of the child is usually not dangerous.For easy sinus bradycardia in children may develop on the background of intoxication, various diseases of the nervous and endocrine systems, and so on.Sinus bradycardia in adolescents is often associated with rapid growth, hormonal surges, vascular dystonia, the beginning of smoking, drinking and other things.But there may be good reason to have sinus bradycardia Sinus bradycardia - how to distinguish normal from pathological state , such as myocarditis.At the same time, as a rule, there are pains in the heart pain in the heart - always consult a physician and dyspnea, so parents go to the doctor.
bradycardia How does a child have
adult bradycardia manifested in heart rate less than 60 beats per 1 minute.In children of different ages HR indicators are different, but in any event the heart rate of the child is higher than that of an adult.In newborn infants, bradycardia is shown a decrease in heart rate to 100 beats per minute in children from 1 year to 6 years - up to 70 strokes in adolescents - up to 60.
Easy bradycardia in children does not usually lead to circulatory problems and did notappears.
In severe bradycardia in the child may appear dizziness, weakness, attention disorders, fatigue, drops in blood pressure, fainting, and semiconscious.When such symptoms on a bradycardia should seek medical advice immediately and examine the child.
severe bradycardia with a sharp slowdown in heart rate may occur as a syndrome of Morgagni-Adams-Stokes equations, which is characterized by sudden onset seizures with loss of consciousness and cardiac arrest time.This syndrome occurs in disorders of the conduction between the atria and ventricles.
The child suddenly there dizziness, dark circles before my eyes, he is pale and in a few seconds lost consciousness, then convulsions, involuntary urination occurs often, cessation of breathing and cardiac arrest.With the restoration of the heart the child quickly comes to mind, but usually does not remember what happened to him.
treatment of bradycardia in children
treatment of bradycardia in children is usually performed only if the associated circulatory disorders (attacks of weakness, dizziness, and so on).I am sure we treat the underlying disease that led to the bradycardia (eg, myocarditis or heart disease).Furthermore prescriber promoting acceleration of heart rate (belladonna, caffeine, etc.).
Bradycardia in a child requires a survey to identify its causes.To appoint such a child treated or not, and to what extent the doctor decides.
