Bradycardia in children — causes, symptoms and treatment
Bradycardia in children occurs regardless of age. With this diagnosis, the reduction in heart rate. A newborn baby's heart rate is reduced to one hundred beats per minute in children of preschool age 70, from teenagers to 60.
Bradycardia in children – causes
This disease develops in a child if he has congenital heart problems. Also, the cause of bradycardia are diseases of the nervous and endocrine systems, increased intracranial pressure and some infectious diseases. Lead poisoning or nicotine are also reasons for the decline in the number of cardiac contractions.
Bradycardia in children also appears with increased vagal tone as a consequence of the pathological process of the myocardium. This phenomenon becomes a cause of reduction of impulses in the sinus node, and eventually formed a nodal rhythm. In addition, a reduction in heart rate may occur when taking propranolol and potassium in large quantities.
Bradycardia in children is divided into several types depending on how to manifest this pathology. There is no absolute bradycardia, that is, the reduction of rhythm constantly, regardless of the patient's condition and the conditions of its location. Relative bradycardia – a reduction in heart rate when exposed to a certain factor. Mild bradycardia in children is a condition that exhalation is replaced by tachycardia. This moderate form of the disease occurs in a child at a younger age, for example by supercooling or by pressure on the eyeballs. It should also be noted that this disease can be physiological or pathological.
Bradycardia in children is manifested as weakness, lethargy, loss of appetite, dizziness, pain in the chest. But the most pronounced symptom is a decrease in the heart rate. Bradycardia is dangerous because the heart in this disease is not able to supply the organs with blood in full measure, and therefore oxygen. If not treated, the disease, in the future it can cause the development of serious violations.
Bradycardia in children is treated based on its type and causes of the disease. For acceleration of the rhythm of the child prescribe a treatment of sulphate of atropine. If the violation of cardiac conductance, prescribe drugs in accordance with the cause of development of this process. In some emergency cases, use electrical stimulation of the heart. If the disease is caused by taking a particular drug, the drug should immediately cancel and hold procedures to eliminate side effects. Most often the physician in the diagnosis of the disease prescribes a medication, adjusting the metabolism of carbohydrates and eliminates oxygen starvation.
Many children aetiology is temporary in nature and easily correctable. In some cases, the child simply outgrows this pathology.
