Violations of cardiovascular activity in children, causes, symptoms and prevention.

The most common heart diseases at an early age are its congenital malformations and myocarditis.

Congenital heart defects are formed at the early stages of embryo development (at 2–8 weeks of gestation) and depend on anatomical disturbances in the structure of the heart, large vessels, and the valve apparatus of the heart. Causes: exogenous effects on organogenesis mainly in the first trimester of pregnancy (rubella, maternal alcoholism, the use of certain drugs, exposure to ionizing radiation, etc.). Symptoms are very diverse and are determined by the peculiarities of the defect, the degree of compensation and the resulting complications. Most often, children are characterized by small stature, physical weakness, often they develop pale skin or cyanosis (cyanosis). Prevention: elimination of possible etiological factors.

Myocarditis, an inflammation of the heart muscle, most often develops in infectious diseases.
Causes: damage to the muscles of the heart (most often viruses), exposure to toxins (with diphtheria), pathological immune reactions (with rheumatism). Symptoms can be turbulent: shortness of breath, palpitations, chest pain, fever (or re-rise in the background of the current disease); but they may be barely noticeable: lethargy, pale skin, "shadows" under the eyes, blue around the mouth, avoidance of physical activity, shortness of breath on exertion, "unexplainable" temperature rises. Prevention: timely treatment of infectious diseases.

Rheumatism is a chronic disease with a primary lesion of the heart and blood vessels and frequent damage to the joints.

Syncope is a mild form of vascular insufficiency caused by hypoxia of the brain.

Violations of cardiovascular activity in children, causes, symptoms and prevention.

  1. Flat feet, causes, symptoms and preventive measures.
    In the normal form of the foot leg relies on the outer longitudinal arch. The inner arch works mainly as a spring, with its help the elasticity of the gait is ensured. If the muscles that support the normal arch of the foot weaken, the entire load falls on the ligaments, which, stretching, simplify the foot. The causes of developing flatfoot can be: 1) rickets, general weakness, impaired tone
  2. REGULATION OF ACTIVITY OF THE CARDIOVASCULAR SYSTEM
    Regulation of the circulatory system is carried out primarily due to changes in the minute volume of blood and the resistance of the regional divisions of the vascular system. The mechanisms regulating blood circulation are conventionally divided into local (peripheral, or regional) and central - neurohumoral. The first regulate the blood flow in organs and tissues in accordance with their functions and metabolism, the second -
  3. Fundamentals of physiology and pathophysiology of the cardiovascular system in children
    The cardiovascular system in children compared with adults has significant morphological and functional differences, which are all the more significant the younger the child. In children, during all age periods, the development of the heart and blood vessels occurs: the mass of the myocardium and ventricles increases, their volumes increase, the ratio of different parts of the heart and its location in the thoracic

  5. Damages of the cardiovascular system in endocrine disorders
    The cardiovascular system is often involved in the pathological process for diseases of the endocrine glands. Functional changes in the heart may prevail in the clinical picture, and a patient with an endocrine disease becomes virtually a “cardiac” patient. Heart damage in endocrine diseases is mainly due to metabolic disorders caused by a lack or excess
  6. Evaluation of the functional state of the cardiovascular system in children and adolescents
    Sports activities make great demands on the child's body. Therefore, specialists, most often pediatricians and rheumatologists, should clearly know the contraindications to classes in sports sections. Below is the pathology in which children are not recommended to play big sports: 1. Congenital and acquired heart defects, valve prolapses of II and III degree and other minor anomalies of development

    Arrhythmias are disorders of heart rhythm and conduction, occur in congenital heart defects, acquired heart diseases, and dysfunction of the central and autonomic nervous system. Classification of cardiac arrhythmias. 1. Violation of the function of automatism - is to change the number of pulses rotating in the sinus node (violation of the formation of an excitation pulse): 1) nomotope violations
  9. Solar and heat stroke. The reasons. Symptoms First aid. Prevention.
    Sunstroke is a condition caused by direct sunlight on the head (usually the occipital-parietal region). Predisposing factors are sultry, calm weather, prolonged exposure of the sun to the head. Symptoms: redness of the face, general weakness; increase in body temperature to 39–400 ° C; severe headache, dizziness; increased pulse and respiration;

An additional role is played by the number of circulary cr, its viscosity. For some reason, it is possible to call a physiologist for a reaction (for example, dilation of blood vessels, change of respiration) or easily detected in blood (radioactive isotopes,
  12. Diseases of the cardiovascular system
    According to statistics, diseases of the cardiovascular system occupy a leading place among the diseases of non-communicable etiology and are the main cause of death (43%). Distinguish diseases developed on the background of congenital defects and acquired. Congenital malformations occur very early and make up only 2.4% of the total number of cardiovascular pathologies. Dogs with congenital malformations
  13. Individualization of the preventive activities of officers to prevent suicide among military personnel
    The main directions of improving the process of pedagogical prevention of suicidal phenomena in the school are: 1. Increasing the level of preparedness of officers for social and pedagogical activity to prevent suicidal phenomena among personnel. 2. Implementation of pedagogical diagnosis and prediction of the risk of suicidal behavior of military personnel. 3
  14. PSYCHOLOGICAL BASES OF PREVENTION OF VIOLATIONS OF MILITARY DISCIPLINES ON SHIP
    The state of military discipline is determined by the whole structure of the ship service and the life of sailors. Of great importance for maintaining a high level of discipline is work to prevent (prevent) disciplinary offenses. The timely identification and elimination of the causes of violations of military discipline is considered by the statutes of the Armed Forces of the USSR as official duties of commanders.
  15. The cardiovascular system
    Features of the structure and functions of the cardiovascular system In infants and young children there are the following features of the structure of the cardiovascular system: after birth, the fetal circulation is rebuilt - the force of pulmonary resistance during pulmonary ventilation, rotation of the shunt in the arterial duct (Botallo duct), closure of the duct and oval holes, with hypoxia in
