Sinus bradyarrhythmia: symptoms and a description of the disease

Sinus bradyarrhythmia occurs when the heart rate decreases to less than sixty beats per minute. In this case, the sinus node acts as a source of pulsation deceleration. At the same time, the normal mode of activity of all cardiac structures and the sequence of operation of the ventricles and atria is maintained. Deviation can be observed in healthy people. For example, in professional athletes at rest, the number of pulse cuts can be less than forty strokes.

Sinus bradyarrhythmia is often a consequence of some diseases. Patients with severe manifestations of the disease may experience dizziness, pain in the heart, cold sweat, weakness, visual impairment, chronic fatigue, fainting states up to complete loss of consciousness.

The disease causes a number of pathologies. The deviation may result in a decreased function of the thyroid gland, associated with an overdose of medicines digoxin, cordaronone, beta adrenoblocker.

The ailment arises from local influences on the sinus node, from inflammatory or degenerative lesions, which can be caused by thromboses or myocarditis of the vessels. Deceleration of the heart rhythm can be associated with myocardial infarction of the posterior wall.

Sinus bradyarrhythmia is a symptom of cardiosclerosis in the elderly. In rare cases, it is observed in cardiac tumors, when there is damage or pressure on the sinus node.

The occurrence of the disease is facilitated by viral diseases, hypothyroidism, myocardial infarction, increased intracranial pressure. However, the main cause of the disease is a lesion of the sinus node, in which there is an increase in the tone of the nervous parasympathetic system.

As a treatment prescribe drug therapy with atropine, isoprotenol, and also use electrocardiostimulation. If clinical manifestations are absent, treatment is not required.

Sinus bradyarrhythmia in children can develop at an early age. The main cause of the disease in children is an increased tone of the vagus nerve, resulting from a pathological process in the myocardium. In some forms, the disease is expressed in children in a constant slowing of the heart rate, regardless of the factors of influence or the condition of the child. In other cases, the diagnosis is made only when the rhythm is slowed by certain factors, for example, hyperthermia.

Bradyarrhythmia in children is a fairly frequent deviation, characterized by the appearance on exhalation of tachycardia. This condition can be caused by exposure to cold. The disease can have both primary and secondary form, when the slowing of the rhythm is associated with other diseases of the body (cerebral edema, myxedema, intracranial hematoma, liver disease).

Most often the child with pathology does not complain about anything. With a pronounced nature of the disease, children may experience headaches, weakness and dizziness. With exacerbations, loss of consciousness is possible, due to impaired inflow to the brain of the blood.

If you have a complaint about poor health, you need to perform a comprehensive examination. With the diagnosis of sinus bradyarrhythmia, regular monitoring of the cardiologist will be required. In cases of seizures, an immediate consultation with a cardiac surgeon will be required, which will consider the question of the appointment of electrostimulation.

In recent years, there has been an increase in the number of children suffering from an illness. But for many, the phenomenon is easily corrected and is of a temporary nature. With the well-being of the child, it is enough to wait a while, and the disease can pass by itself.
