Causes of tachycardia in pregnancy

Factors and conditions of the body, which cause an increase in heart rate very much. The main ones are the following:

  • Allergic reactions to various drugs used for the future mom.
  • Excess body mass that occur during gestation of the fetus.
  • Anaemia in pregnant women.
  • Inflammatory diseases of the organs that arise due to reduced immunity of the woman’s body.
  • Pregnancy complications (placental abruption, threatened abortion, hemorrhage, toxemia).
  • Changes in the nervous system.
  • Physical displacement of the heart due to the fact that the pregnant uterus lifts the whole abdomen up to the diaphragm.

All the reasons for the increase in heart rate during pregnancy is not known. Proved only the fact that the cause of the tachycardia is an increased level of adrenal hormones, which causes a rise in blood pressure and increased heart rate. During pregnancy even small physical load force a woman to apply considerable effort to their implementation. It is also a cause of tachycardia.

Symptoms

Many women do not pay attention and do not attach importance to the symptoms associated with tachycardia. On the one hand, this is correct, however, when the frequently occurring bouts of unexplained changes in health status still need to be wary of. A slight increase in heart rate during pregnancy is a normal variant. This is due to the increase in the volume of blood flowing through the heart and the necessity to enrich it with oxygen.

To dangerous symptoms of tachycardia during pregnancy, in which the obligatory consultation of the specialist are:

  • frequent dizziness;
  • vomiting and changes of the gastrointestinal tract in the form of diarrhea or constipation;
  • numbness of parts of the body;
  • pain in the heart.

Tachycardia in early pregnancy early pregnancy frequency of contractions of the heart muscle is rare. In this case, the main reason is the breakdown, experiences and beginning the hormonal changes. If you encounter a long persistent tachycardia cause can be chronic diseases of the heart and blood vessels.

To resolve an attack of tachycardia in the early stages of pregnancy, you need to calm down and relax. It is recommended to close eyes and for several minutes, slowly making the deep breaths. If this procedure is ineffective, the woman is assigned the soothing drugs of plant origin.

Tachycardia in late pregnancy

Towards the end of pregnancy, the tachycardia appears almost all. The leading reason for its occurrence is the displacement of the heart due to the high location of the uterus. This condition is not pathological and requires no correction.

Late-term tachycardia may appear on a background of reception of medicines. It’s dangerous the possibility of premature birth. Palpitations often occur when the use of vasoconstrictor drugs for the treatment of rhinitis.

At the end of pregnancy meds to a lesser extent affect the fetus, however, even in this case, for the treatment of persistent tachycardia with a preference to herbal medicines.

Paroxysmal tachycardia in pregnancy

This condition is characterized by a sharp increase in heart rate. However, over the minute your heart makes from 130 to 200 cuts. Paroxysmal tachycardia is characterized by paroxysmal course. Quite often, the heart rate alone decreases to normal without medication.

During pregnancy, paroxysmal tachycardia may have the following symptoms:

  • noise in the ears;
  • sudden dizziness until the complete loss of consciousness;
  • General weakness and lowering blood pressure;
  • shortness of breath, pain and strange sensations in the heart region;
  • nauseam and loss of coordination.

Diagnosis

The implementation of the electrocardiogram during pregnancy in the occurrence of tachycardia during pregnancy is necessary to determine the level of hemoglobin and red blood cells. For this woman needs to get a blood test. In the absence of deviations the next step is to determine the level of thyroid-stimulating hormone (thyroid hormones).

In addition, be sure to perform a electrocardiogram (ECG) to determine the type of tachycardia. Sometimes prescribed Doppler. With the help of ultrasound or echocardiography examines the heart valves and heart chambers.

After obtaining all the diagnostic results by a doctor is accepted the decision on appointment as efficient as possible, but minimally affecting the unborn child of a drug.

First aid for tachycardia and the principles of its treatment in pregnant women

Due to the fact that the main reason for the tachycardia that occurs during pregnancy – mental stress, first aid is to relax women. Enough to rest, to sleep. In the long constant palpitations is important to eliminate all triggers. It is necessary to minimize the consumption of coffee and strong tea.

Due to the fact that in the first months of pregnancy, the tachycardia appears to cause increase in hormonal levels to prevent increased heart rate appropriate receiving sedative drugs. The last time the most effective vitamins and minerals. This is due to the enhanced growth of the fetus and increased need for nutrients.In particular, we are talking about the preparations containing potassium and magnesium. Any activities aimed at strengthening women’s health, can normalize cardiac function of the mother. Aside from the above, it is very important proper nutrition during pregnancy.

Prevention of tachycardia and its complications during pregnancy

To prevent tachycardia quite often simply enough to normalize the mode of activity of women. For this, in addition to adequate rest and regular walks on fresh air, it is important to control their weight. From the beginning of pregnancy you can start to perform a special set of physical exercises to keep your body in shape.

The diet you need to add cereals vegetables and fruits. Deep and calm breathing to allow you to normalize the autonomic nervous system and prevent tachycardia.

Some variants of tachycardia can cause loss of consciousness. So important is the study and implementation of certain methods to prevent fainting. These include the following activities:

  • to get some fresh air or to provide increased access thereof;
  • moisten face and neck with water;
  • to take the maximum horizontal position (to sit or lie down).

Forecast

The risk of changes of cardiac activity in the form of increased heart rate depends on a number of factors. These include:

  • age pregnant;
  • gestational period;
  • the presence of heart disease.

In the latter case, perhaps the development of supraventricular tachycardia that can negatively affect the future health of the mother. If the physiological tachycardia, the prognosis is generally favorable.

Any long flowing tachycardia should alert the mother. Frequent episodes also imply the need for medical diagnosis of pathology. Thus, we can say that tachycardia during pregnancy in most cases is physiological, does not require special treatment and has a favorable prognosis.
