Tachycardia in pregnant women at different periods

Causes and symptoms of a rapid heart rate during pregnancy

Pregnant women often notice a rapid heartbeat - more than 90 beats per minute. This is tachycardia. It is recorded even in an unborn child during intrauterine development, but there is no direct connection between the accelerated rhythm of the mother and the baby.

The so-called physiological tachycardia when carrying a child is very common. The body thus adapts to its new state. If the acceleration of the rhythm happens with a rare frequency and quickly pass without bringing any unpleasant sensations with it, there is nothing for a pregnant woman to worry about. By the way, the expectant mother does not always notice them.

Frequent heart contractions cause a lot of reasons, therefore, patients with severe discomfort and recurring attacks must be examined.

It is necessary to take into account some of the nuances:

1. In pregnant women in the first trimester, tachycardia occurs due to an increase in circulating blood volume and cardiac output to ensure the necessary blood flow to the fetus.
2. The increased production of thyroid and adrenal hormones affects the heart rate.
3. There is a change in metabolism and a rapid increase in body weight.
4. Anxiety and stress increase the release of adrenaline, which is manifested by a rapid heartbeat.
5. Under the influence of progesterone, the vascular tone weakens and the pressure decreases, compensatory tachycardia occurs.
6. As the fetus grows, the diaphragm rises, breathing and heartbeat become faster to deliver the required amount of oxygen.
7. Iron deficiency anemia is manifested by dizziness and rapid pulse due to hypoxia.
8. A sudden change in position and squeezing of large vessels by the uterus at a later date lead to sudden weakness and tachycardia, which disappear when the position of the body changes.
9. Some medicines affect blood pressure and heart rate. Before taking any medications, you should consult a gynecologist.
10. Excessive physical activity worsens the condition.
11. Nausea, severe headache and heart palpitations during late pregnancy can be signs of toxicosis.

Tachycardia during pregnancy can be accompanied by:

• weakness, weakness;
• nausea (vomiting is possible);
• pain in the heart;
• fainting;
• anxiety, increased arousal;
• legs and arms lose sensitivity;
• tends to sleep all the time;
• dizzy;
• indigestion occurs.

If at least one of these signs is present, a pregnant woman should see a doctor. Tachycardia of a pathological nature can be caused by various diseases that can harm an unborn child. Having found such a violation of cardiac activity, it is necessary to look for the cause and be treated.

If you want to know everything about tachycardia, we advise you to watch the video, which is below the link. Causes, symptoms, diagnosis and signs that it is time to see a doctor - about all this in 7 minutes. Happy viewing!

Why does tachycardia occur during pregnancy? There are several reasons:

• dysfunction of the thyroid gland, which is manifested by excessive production of hormones;
• infectious diseases, the development of sepsis;
• respiratory diseases (for example, bronchial asthma);
• Iron-deficiency anemia;
• excess weight;
• kidney disease;
• prolonged physical or mental stress;
• side effects of drugs or vitamin complexes;
• early toxicosis, which is accompanied by vomiting and dehydration;
• intoxication caused by the inflammatory process and an increase in body temperature;
• diseases of the heart and blood vessels;
• neuroses of pregnant women, increased emotionality;
• internal or external bleeding;
• smoking, drinking alcohol or drugs, coffee mania.

Usually, a pregnant woman herself can accurately determine the cause of the "fluttering" of the heart: if at the same time her hands tremble, most likely, she experienced a strong emotional outburst, increased sweating occurs after a cup of strong coffee, and weight loss and appetite decrease - with toxicosis or hormonal disorders. However, joking with such things is not worth it, and a doctor's consultation with tachycardia is necessary. Not only the expectant mother is in danger, but also her baby.

How to understand that a condition threatens health

In the first trimester tachycardia in a pregnant woman rarely occurs, and most often it is associated with the manifestation of early toxicosis. But, perhaps, this is a sign of a latent disease. Both can be dangerous for both the mother and the child, a doctor's consultation will not be superfluous. In the case of a physiological increase in heart rate, there is no threat to a pregnant woman.

A pathological malfunction of the sinoatrial node indicates the presence of the following deviations:

• the heart cannot withstand the stress that has increased with the appearance of the fetus;
• anemia;
• arterial hypotension;
• reflex reaction of the myocardium to compression;
• nervous disorders;
• toxicosis of pregnant women;
• taking some medications;
• endocrine diseases (in particular, thyrotoxicosis);
• imbalance between the mother's energy needs and nutrition;
• violation of water and electrolyte balance.

At a later date gestation, rhythm disturbance often has a natural (physiological) explanation: the uterus grows, the fetus increases in size and requires increased nutrition and oxygen supply. Attacks should not scare a pregnant woman, but extra caution and attention to your health will not hurt: even a seemingly insignificant deviation from the norm can affect the outcome.

Complications

1. Delayed fetal development.
2. Premature birth or miscarriage.
3. Death of the fetus in the mother's abdomen.
4. Difficult childbirth.

Correct actions

Tachycardia in the range of 85-95 beats per minute does not cause pain or discomfort. Many women experience weakness and shortness of breath that go away after rest. An increase in heart rate above 100-120 beats during pregnancy is dangerous. This can lead to severe shortness of breath and fainting.

If you feel your heart is beating too fast, try to calm down. Stop physical activity, lie down, breathe slowly and deeply, open a window for fresh air, drink a glass of water. In most cases, this will be enough to cope with the attack.

The breathing exercise "Square" helps a lot. It is necessary to act according to the following scheme:

1. Breathe in for 5 seconds (this is an average, you will have to experimentally establish your rate).
2. Hold your breath for 5 seconds.
3. Exhale for 5 seconds.
4. Hold your breath again for the same time and then repeat this cycle several times.

The following autonomic reflexes of the vagus nerve can also be used to decrease heart rate:

• lightly press on the eyeballs several times - after that, the heart rate should return to normal;
• run the tip of your tongue over the palate 7-8 times, this also calms the heartbeat.

Experimentally determine the best method and use it to relieve attacks of sinus tachycardia. If there is no effectiveness and discomfort persists, call a doctor. Wherein:

1. Lie down or sit down while waiting for the doctor.
2. If tachycardia appears in a supine position, change position, turn onto your left side, and place a pillow under your back.
3. Washing with cool water helps to normalize the pulse.
4. If you feel dizzy, take a half-sitting position with a pillow under your feet.
5. Do not take medications without a doctor's prescription.

What to do for prevention

• Quit smoking, alcohol, energy drinks, caffeinated coffee completely;
• strong black and green tea - in small quantities;
• physical activity should be moderate, without sudden and intense movements;
• during pregnancy, you should not run, lift weights;
• slow walks in the fresh air, swimming are recommended;
• nutrition should be balanced, with a sufficient amount of proteins, fats and carbohydrates;
• to prevent dehydration, you should drink at least 2 liters of fluid per day;
• night rest is obligatory not less than 8-9 hours of sleep, daytime 30-60 minutes.

Forecast and conclusions

Tachycardia caused by changes in the body of a pregnant woman usually resolves after delivery. If preventive measures are observed (daily regimen, nutrition, rest, emotional peace), there will be no consequences of such a temporary violation.

The danger is carried by attacks of rapid heartbeat, which are a sign of serious pathologies of internal organs, including the cardiovascular system. In general, the prognosis of tachycardia in pregnant women depends on the woman's age, the stage of the concomitant disease, the period at which the deviation occurred, and the treatment being performed. The situation is complicated by the fact that in many cases the necessary therapy cannot be carried out, since most drugs are incompatible with pregnancy.

There are cases when a woman is diagnosed with a condition in which carrying a child and its birth becomes impossible due to a real threat to the life of the expectant mother.

The heart is the main human organ. In a pregnant woman, it must be healthy and capable of withstanding the forthcoming stress. Therefore, the slightest deviation in his work needs special attention and control. If tachycardia is uncomfortable or indicates an additional medical condition, it must be treated. An important role in this is played by the behavior of the woman, her understanding of her responsibility to the unborn baby.
