Sinus arrhythmia of the heart

One of the violations of the normal activities of the heart is the sinoatrial (or sinus) arrhythmia. This condition can be a manifestation of pathological changes in the body, and may be a normal variant that often occurs. So consider why there and what is dangerous sinus arrhythmia.

The human heart in norm reduces to the correct sinus rhythm, which specifies the sinus node of the heart conduction system. The frequency of this rhythm in an adult ranges from 60 to 90 beats per minute. An indication that the rhythm is right, is the presence of teeth R and equal to the spaces between the teeth R-R in the electrocardiogram (ECG).

If the intervals R-R ECG are not the same and the difference between them exceeds 0.1, it means that the human sinus arrhythmia of the heart (the network can see the other names of this type of arrhythmia, for example, sinusoidal, sinusoidal, however, they are not quite right). Under this condition, the heart beats faster or slower, but the reduction of all parts of the heart occurs consistently and correctly.

Reasons

As mentioned above, sinus arrhythmia is often a normal variant, but may be the manifestation of a number of pathological conditions. These include:

Hypertension in the past now?

Cardiologists risk to remain without work — hypertension now curable!

  • vegetative-vascular dystonia;
  • the lack of some chemical elements in the body (primarily magnesium and potassium);
  • hormonal disorders;
  • anemia;
  • hypoxia;
  • disorders in the functioning of the thyroid gland;
  • physical and emotional exhaustion;
  • diseases of the spine and other ailments.

After treatment of these pathologies arrhythmia usually disappears, and the heart again begins to beat properly. That is a special treat, this condition does not require and the body as a whole is not harmful, what can be said about its causes. It is also worth noting that in old age a pronounced sinus arrhythmia may be a sign of infarction, and other diseases of the heart (which will be noticeable on EKG), and in alternation with significant bradycardia (decrease heart rate) is a neurosis that requires special treatment.

Sinus arrhythmia as a normal variant

Physiological sinus arrhythmia (ie, normal variant) is quite common in childhood and adolescence that is associated with the development of the boys hormonal and temporary imbalance in the functioning of the vegetative nervous system. According to some authors, this abnormal heart rhythm to a greater or lesser degree of intensity is observed in more than 90% of absolutely healthy children of all ages.

In addition, there is respiratory sinus arrhythmia – physiological phenomenon, which is especially noticeable during slow deep breathing and can be detected in any person. Therefore, to determine whether there is a connection between the rhythm and the act of breathing, the health care provider asks the patient while recording the ECG to hold your breath.

Sinus arrhythmia during pregnancy

Often in pregnancy when the examination of the heart also reveals a sinus arrhythmia. The main reasons of its occurrence – an electrolyte imbalance and hormonal changes that occur in the body of every expectant mother. To resolve rhythm disturbance without drugs, doctors recommend that women in the position to eat right, have a rest, more walk in the fresh air and, if necessary, to take special vitamin-mineral complexes. No other treatment of this condition does not require and is not dangerous for the baby. To completely eliminate any suspicion, you can do the ECG in the dynamics and be sure to regularly take a blood test in order not to miss the anemia.

Sinus arrhythmia and vertical position EOS

This conclusion after ECG examination of the children and adolescents can be seen quite often. If no complaints, the child feels well and the results of other tests are in the normal range, it is not necessary to regard this condition as a manifestation of pathological changes in the body.

As mentioned above, sinus arrhythmia in children is common, and the vertical position EOS (electrical axis of the heart) is typical for people of slim build, with which mostly are children. That is the conclusion of the ECG can be considered as a normal variant.

What are the symptoms?

The arrhythmia of this type is usually found accidentally during ECG examination. However, some people turn to doctors because they have specific complaints and symptoms:

  • feeling short of breath;
  • dizziness;
  • periodic fainting;
  • the darkening of the eyes;
  • faults in work of heart (patients say heart skips a beat, pounding);
  • discomfort in the chest (this may be pain, heaviness).

If there are any pathological symptoms and data about the violation of the rhythm by ECG, is a more detailed heart exam. It is desirable to make EchoCG, Holter monitor and repeat EKG. In the absence of any symptoms, to make sure that sinus arrhythmia is a normal variant, doctors recommend that you consult a cardiologist and get a complete diagnosis.
