Neurogenic Bradycardia

In non-cardiac diseases, various forms of rhythm disturbance may develop. Often diagnosed with neurogenic bradycardia, which is not difficult to determine with the help of common research methods. When properly administered therapy does not cause dangerous complications.

Neurogenic bradycardia is a symptomatic pathology that develops against extracardiac diseases. If the main illness does not pose a threat to human health then you can not worry about the long-term consequences. The only thing that is important is to start the right treatment right from the beginning.

When bradycardia, the heart rate is lower than 60 beats / min in adults. In children, heart rate is determined depending on the age, for example, until one year, the pulse rate below 110 beats / min is considered abnormal.

In the process of diagnosis, standard methods are used, primarily electrocardiography. Additionally, laboratory tests, load tests, ultrasounds of the heart, as well as specific research methods, will help to establish the exact cause of the pathological condition.

Description of neurogenic bradycardia

During the development of the pathological state, the following forms of the slowed-down rhythm can be observed: sinus and non-sinus. For the latter species, the formation of a blockade of impulses is characteristic, therefore such a violation of the rhythm in clinical practice is considered implicit bradycardia.

Sinus bradycardia is characterized by a decrease in the activity of the sinus node. Such a form often develops against a background of various vegetative disorders, especially with an increase in the tone of the parasympathetic department of the nervous system. If disorders of other organs and systems are observed, then a sinouricular conduction disorder may occur.

Symptoms of neurogenic bradycardia

It is possible to determine the development of bradycardia on such features as increased fatigue, pronounced feeling of weakness, lack of attention and reduction of memory. Also, the patient starts to cope with the usual duties worse, in some cases it is difficult to perform physical exercises.

Moderate and insignificant bradycardia does not cause, as a rule, hemodynamic disturbances, as a result of which the clinic under these conditions is weakly expressed.

Depending on the underlying condition, the following symptoms may occur:

  • cold sweat;
  • pain sensation in the region of the heart;
  • sharp jumps in blood pressure;
  • difficulty breathing;
  • minor visual disturbances.

During the attack, various periods of contraction can be traced. If there is severe anxiety, a sudden dizziness, a semi-bad state, then you should immediately contact a doctor.

Causes of neurogenic bradycardia

In the development of pathology often involved various pathological conditions, not associated with diseases of the heart and blood vessels. Most often, neurogenic bradycardia occurs on the background of the following pathologies:

  • Neurosis-like states that are characterized by chronic course and predominance of psychogenic factors of influence.
  • Wagon-insulatory crises associated with disorders of the autonomic nervous system.
  • Bleeding into a subarachnoid space, often due to traumatic lesions of the brain.
  • Inflammation of the labyrinth in the inner ear.
  • Colic of different origin (hepatic, renal, intestinal).
  • Ulcerative diseases of the stomach and duodenum.
  • Hernia of the esophageal-diaphragm hole.
  • Reflex reactions affecting cardiac activity (strong supercooling, pronounced pain).
  • Convalescence performed after severe protracted diseases.

The development of neurogenic bradycardia is associated with frequent stressful situations. If a person is emotionally labile, then it's much more difficult to treat the pathology. The same situation is with the presence of bad habits and other similar risk factors.

Diagnosis of neurogenic bradycardia

During the medical examination of a patient with neurogenic bradycardia, the percentage of reduction in heart rate is found. Electrocardiography is mandatory for specification of the diagnosis, which determines the following changes:

  • undisturbed tooth P with normal atrioventricular conductivity (corresponds to sinus arrhythmia);
  • reduction in heart rate.

Holter monitoring helps to clarify the diagnosis. With its help, during the day or two, an ECG is recorded, after which the data are analyzed for the presence of not expressed violations of the rhythm. If the underlying disease is associated with hormonal disorders or disorders of the gastrointestinal tract and other organs other than the heart, then methods of diagnosis using the type of laboratory tests are used.

Treatment and prevention of neurogenic bradycardia

Specific therapy is performed only in the case of severe pathology. Depending on the severity of the process, the treatment can be attributed to the outpatient, or is carried out in the profile cardiology department.

Frequently used methods of treating neurogenic bradycardia:

  • Medicinal therapy - aimed at eliminating the underlying disease, for which the appropriate drugs are prescribed. To eliminate the symptoms of a slowed rhythm, medications such as alupenta, atropine, and iridadine are used. If there are contraindications to the last two drugs, then ipratropium ephedrine is used.
  • Surgical treatment - is carried out in the extreme case when the patient does not help the medicine or there are serious contraindications to their taking. As a result, the patient is given a pacemaker implantation, which helps to prevent sudden cardiac arrest.

In conducting prevention, the following recommendations should be taken into account:

  • the absence of bad habits in the form of alcohol and smoking;
  • properly scheduled day mode;
  • a full-fledged meal with the contents of the heart's products;
  • conducting medical treatment for the elimination of concomitant diseases;
  • taking medications only after a doctor's consultation.
