Tachycardia is called the increase in the heart rate of the .This is not a disease, but a manifestation of a hidden ailment.
The norm for a healthy person in a calm state is the indicator 60-80 cuts in 60 seconds .With tachycardia, this indicator increases to 90 contractions. In recent years, this threshold has been raised to 100 blows.
Forms: sinus, atrial and paroxysmal
There are three forms of tachycardia:
- sinus , in which the rhythm of the heart remains the same, and the number of cuts increases over 90 beats per minute;
- atrial , superverticular, supraventricular, in which strokes increase to 140-250, the source is in the atria;
- paroxysmal , in which the rhythm is accelerated to 140-250 contractions, the source of the problem is in the ventricle of the heart.
Causes of malfunctions in pregnant women, risk factors
Development of tachycardia of the heart during pregnancy is facilitated by:
- increase in blood volume, which causes compensatory heart rate increase;
- the hormonal background changes( the development of estrogen is activated), which causes myocardial excitability;
- increases in size of the uterus, limiting the mobility of the diaphragm, increasing abdominal pressure and changing the position of the heart.
To risk factors also include:
- excess weight;
- anemia( anemia);
- allergic reactions of the body to medicinal and vitamin preparations;
- is an excessive thyroid function;
- bronchial asthma;
- drinking coffee, tea;
- infection and inflammation of the respiratory system;
- bleeding with ectopic pregnancy, trauma, early placental abruption;
- toxicosis, which causes dehydration and depletion of the body;
- sharp rise in body temperature( one degree increases the frequency of cuts by 10-12 units);
- frequent stress, excitability, anxiety;
- infection, sepsis;
- bad habits - alcoholism, drug addiction, nicotine addiction.
Danger to the mother and fetus
Tachycardia - is a common phenomenon, especially in the 3rd trimester of the pregnancy. In the early stages of tachycardia during pregnancy is rare, but in late - from the sixth month - the deviation of the indicator from the norm in some cases reaches 20 strokes.
This is associated with the loads experienced by the heart of the mother .So, the body needs to provide more blood to the uterus. Thanks to this, the fetus gets enough nutritious components.
Still, tachycardia is an insidious phenomenon that can not be ignored by .In fact sometimes it is caused by aggravated ailments, heart and vascular diseases. This threatens the life of both mother and fetus. Also difficult births are possible.

Pathological tachycardia in pregnant women is associated with anemia, in which the hemoglobin level falls below 110 g / l , as well as with blood loss.
Diagnosis
When a pregnant woman is treated with tachycardia complaints, a number of laboratory and instrumental studies are performed:
- blood test( general) to clarify the level of erythrocytes and hemoglobin - to exclude blood diseases( leukemia, anemia, etc.);
- blood test the content of hormones for determining thyroid function;
- urine analysis - on the subject of adrenaline decomposition products;
- electrocardiogram( ECG), including Holter( daily observation) - reveals cardiac pathologies;
- rheography - determines the state of blood vessels, their tone, elasticity, blood filling;
- samples with load - help assess the condition of the myocardium;
- echocardiogram or ultrasound of the heart to assess the state of the heart muscle, valves, the presence of vices, other chronic diseases.
Differential diagnosis excludes diseases:
- atrial fibrillation;
- microinfarction;
- cardiosclerosis;
- anemia;
- hypertrophy of the left ventricle( on the ECG).
In addition to a woman's examination, tracks the fetal condition of .It is useful to make ultrasound of the fetal heart during pregnancy, which you can read about in a separate article.
