Depression of the ST segment as a manifestation of vegetative dystonia

At the same time, it is possible that depression of the ST segment, caused by an increased tone of the sympathetic division of the autonomic nervous system, also expresses a real circulatory failure due to a narrowing of the small coronary arteries. Perhaps the cause of their narrowing during stress is not catecholamines, but, for example, neuropeptide Y, released by the endings of the sympathetic nerves under the influence of a strong adrenergic effect, which causes narrowing of the small coronary arteries.

Depression of the ST segment as a manifestation of vegetative dystonia

  1. Rhythm and conduction disorders as a manifestation of autonomic dysregulation
    Often, during Holter monitoring, there is a deficiency that is dependent on an increased vagal tonus. In this case, substitute rhythms are recorded, including from supraventricular pacemakers, combined with slowing of AU-conductivity, as well as with an AU-blockade not exceeding a degree of blockade of the Venkebach type. This deficiency occurs in young patients with a healthy heart.
  2. Vegetative dystonia syndrome
    Vegetative dystonia syndrome can be of constitutional nature, can occur with endocrine changes of the body (puberty, menopause), diseases of internal organs (pancreatitis, gastric ulcer and duodenal ulcer, etc.), endocrine (diabetes, thyrotoxicosis), allergic and various diseases of the disease, and endocrine diseases (diabetes, thyrotoxicosis), allergic and various diseases of the disease. nervous system. In vegetative syndrome
  3. Vegetative-vascular dystonia
    The sympathetic division of the autonomic nervous system regulates mainly adaptation-trophic processes in situations requiring intense mental and physical activity. The parasympathetic division of the autonomic nervous system shows its main function outside the period of intense activity of the organism, mainly during the "rest" period, and regulates anabolic processes, insular
  4. Sinar vegetative-vascular dystonia (crises)
    Vegetative-vascular dystonia (VVD) - a set of symptoms that reflect the dysfunction of the vegetative regulation of vascular tone and, consequently, the functions of other systems. Leading symptoms: • fluctuations in pulse, blood pressure; • gastrointestinal dyskinesia; • fatigue. Etiology. The IRR syndrome may be of constitutional nature, but more often caused by other factors: endocrine restructuring of the body (menopause);
  5. Other changes in the repolarization period on ECG due to vegetative dystonia
    The occurrence of a U wave on an ECG is associated with hypersympathicotonia with an amplitude of> 1 mm. The U tooth is on the descending knee of the T wave, and sometimes exceeds it. In the hypersympathicotonia state, U and T teeth are characterized by variability over hours and even minutes of registration. It should be remembered that the U wave is of a slightly different configuration, which is recorded for a high T wave, more often in leads

  7. How is vascular dystonia
    "Hello, Doctor! I am 34 years old. Last year I experienced a divorce, which was very hard. After that, I had to go to the hospital with a diagnosis of cardioneurosis. Despite the fact that more than a year has passed, I occasionally have unpleasant feelings: there are jumps in blood pressure from normal, 65 and 122, to 90 and 155 mm Hg. Art., changes in heart rate from 48 to 90 beats in
  8. How to help a depressed person?
    Before assisting anyone, it is necessary to check whether a person wants to be helped. People who are in deep depression usually do not want any help. Attempting to help such a person and his refusal to help cause us bitterness and frustration. Most often, these people say: “Leave, go about your business. I am fully capable of adjusting my life myself. I do not
  9. Disadaptive manifestations in soldiers with PTSD as a socio-psychological problem
    The consequences of military actions for the personality of a serviceman could be much weaker if it were not for the emerging negative public opinion regarding former combatants. Public opinion is formed in close dependence on the scale of the military conflict. An analysis of the psychological aspects of the first and second world wars shows that “with the onset of military events of this kind
  10. Integration of the personal and professional components of consciousness as a manifestation of human acme
    One of the applied aspects of the problem of the formation of individuality, that is, the process of integrating the basic characteristics of a person as an individual, personality and subject of activity, is the question of the formation of the individuality of a professional at the stage of study at a higher educational institution, of achieving subject acme. At the stage of university professional training, when students are not yet professionals,
  11. CARDIOPSYCHONEUROSIS
    Neurocirculatory dystonia syndrome is not a nosological form, but only syndromally reflects the presence of constitutional or acquired autonomic dysfunction. Synonyms: vegetative vascular asthenia, vegetative-vascular dysfunction, dysvegetosis, amphodistonia, vegetative lability, vegetative ataxia, neurovegetative dystonia, sympatosis, vegetonuroses, diencephalosis.
