Sinus tachycardia in a child

Today, the children of diseases of the cardiovascular areas to meet not less than adults. One of these abnormalities include sinus tachycardia. The so-called disease in which the baby’s heart rate increases up to 100 – 160 beats per minute (normal is 80) for accelerating the work of the sinus node is the primary feature of the «arm» of the heart muscle.

There are a number of conditions in which an increase in heart rate (heart rate) is considered normal. The heart beats faster after:

  • emotional shocks (both positive and negative, including the case of pain syndrome);
  • physical activity;
  • stay in a stuffy room;
  • the increase in body temperature;
  • ingestion of various medications (if instructed).

Sinus tachycardia: what is it?

Tachycardia is called the acceleration of the heart and subsequent increase in heart rate. If sinus tachycardia is the cause of this phenomenon is the acceleration of the main body of the heart — the sinus node. In this case, sinus rhythm was acceptable.

In babies most often this condition is not worrisome and is associated with excessive swaddling, overheating of the child, pain, medical examination, etc. In some cases, sinus tachycardia cause pathology of the Central nervous system, myocarditis (inflammation of the myocardium), hypoglycemia (lower blood sugar below normal) and other diseases.

Hypertension is no longer a disease?

Doctors are shocked by the statement, the chief cardiac surgeon in the country Leo Beaucaire.

Adolescent development mechanism of the acceleration of the heart is slightly different and can be associated with too rapid growth of the organism, physical and emotional stress and other situations.

Associated symptoms

In addition to the clearly-defined acceleration of the heart rhythm, which can be identified by counting the pulse, in children with sinus tachycardia also experience the following symptoms:

  • pain in the region of the heart (the sternum);
  • weakness and General malaise;
  • headache;
  • shortness of breath, feeling of lack of air;
  • loss of consciousness;
  • fatigue, etc.


The first thing you need to do to detect the disease in a child is to contact your pediatrician. He will analyze the present symptoms, will measure heart rate and blood pressure in a young patient and, if necessary, will appoint a cardiologist.

What can you recommend a cardiologist? In the first place – electrocardiogram. The ECG will be visible to the frequency and rhythm of heartbeats. It is a safe, fast and effective method of diagnosis not only sinus tachycardia, but also of cardiovascular pathologies as a whole.

Also use the methods ECHO (one of the varieties ultrasound) to assess the state of the organ, detecting externally visible pathologies; the EP study (electrophysiology study) to help determine the mechanism of development of increasing heart rate and cause conduction disorders of the heart; General and hormonal blood tests; EEG (electroencephalography) of brain — to exclude a pathology of the Central nervous system, etc.

Treatment of sinus tachycardia

A mild form of the disease, when the heart rate increases slightly and is not a major concern of the patient, it is possible to do without special drug therapy. It will be enough just to monitor the condition of the child, systematically to measure his pulse to monitor the development of the disease, in time to visit a cardiologist.

It is also necessary to review the diet — to exclude from the diet of fatty, fried and spicy food and caffeinated drinks (black tea, cocoa and coffee). No harm will be moderate exercise, the entry in a certain section. Not only will this improve the General health of the patient, but also help to prevent the increase in its weight, which adversely affects the child’s heart.

Overcame hypertension for 1 month

After 10 years of struggle with the disease Oleg Tabakov has told how was able to get rid of hypertension.

In some cases, therapy is still needed. If tachycardia is associated with anemia (anemia), prescribers with a high iron content. Mental etiology (when the disease is provoked by nervousness and stress) — sedative medicines. A fever requires treatment with antipyretic agents.

In patients with more severe manifestations may experience bouts of tachycardia, accompanied by shortness of breath, feeling of lack of air and other manifestations. In such situations, it is necessary to free the child’s chest, removing or unbuttoning the clothing, ensure fresh air intake (for example, to open the window or get out of a stuffy room into the street).

Despite the fact that sinus tachycardia is not true for a number of life-threatening pathologies, it requires monitoring and timely assistance. Otherwise, you may develop heart failure, threatening serious health problems.
