Right ventricular hypertrophy

Right ventricular hypertrophy - a pathological condition associated with increased myocardial which can  Stage right ventricular hypertrophy
 lead to serious disease.

Changing the size of the right ventricle due largely to the growth of cardiomyocytes (heart specialized cells) and is combined with various cardiovascular diseases.

Causes of right ventricular hypertrophy

The reason for increasing the size of the right ventricle can be congenital or mitral stenosis heart. Most often, right ventricular hypertrophy observed:

  • Children on the background of various congenital heart defects;
  • In adults, on the background of valvular heart disease and lung disease, are complicated by disorders of the heart.

Depending on the severity of the disease and its development characteristics can be observed different configurations disease. Among the main causes of right ventricular hypertrophy release:

  • Pulmonary hypertension, which causes an increase in pressure in the pulmonary artery. This causes shortness of breath, dizziness and fainting;
  • Tetralogy of Fallot, which is observed in children from birth and may continue throughout the first year of life. This congenital heart defect, causing blue baby syndrome, characterized by impaired blood flow from the right ventricle;
  • Pulmonary valve stenosis, in which there is disruption of blood flow from the right ventricle into the artery;
  • Ventricular septal defect, which is why there is a mixture of two parts of blood. This causes a lack of oxygen, which leads to increased work of all parts of the heart, including the right ventricle.

Among the lung diseases which can lead to the development of this disease, is isolated:

  • Fibrosis and emphysema;
  • Chronic bronchitis and pneumonia;
  • Pulmonary fibrosis;
  • Bronchial asthma.

Signs of right ventricular hypertrophy

Right ventricular hypertrophy is quite a rare heart disease. In addition, signs of right ventricular hypertrophy are extremely difficult to detect on an electrocardiogram as the mass of the right ventricle is about three times less than that of the left, whose electrical activity prevails.

Signs of increasing the size of the right ventricle can be detected only with a significant increase in its mass. Accordingly, the following types of right ventricular hypertrophy:

  • Pronounced hypertrophy, in which the right ventricle is much greater than the mass of the left;
  • Medium Hypertrophy in which, with increased size of the right ventricle recorded therein a slower flow of excitation as compared with the left ventricle;
  • Moderate hypertrophy at which there was a slight increase in size of the right ventricle.

The initial stages  Signs of right ventricular hypertrophy are extremely difficult to detect on an electrocardiogram
 development of right ventricular hypertrophy have greased the symptoms, and in some cases the symptoms are virtually absent. However, as the disease, accompanied by a steady increase in the size of the right ventricle, the following symptoms appear:

  • Shortness of breath, which is combined with chest tightness and pain;
  • Sudden attacks of vertigo, which may be accompanied by loss of consciousness;
  • Violation of the heart rate, which can be described as the "heart flutters in my chest," or feeling that a few punches missed;
  • Pronounced swelling of the feet.

Treatment of right ventricular hypertrophy

Against the background of right ventricular hypertrophy therapy should be directed primarily at the reasons causing it, namely:

  • On removal of the pulmonary valve stenosis;
  • On the normalization of the lung;
  • In the treatment of heart diseases.

In addition, the treatment of right ventricular hypertrophy and should include symptomatic therapy aimed at normalizing blood pressure and heart rate, to maintain the heart muscle and its extra power.

Generally, surgical treatment is indicated in cases when an increase of the right ventricle is heart disease. Such operations are usually conducted in the first year of life after diagnosis.
