High pulse in pregnancy

During pregnancy the work of many systems of the body, including the cardiovascular system, which undergoes serious changes, including an increase in the heart rate, is activated. However, a high pulse often indicates a cardiovascular disease that can be hidden. Therefore, it is worthwhile to know the signs, at the appearance of which you should immediately consult a doctor.

A high pulse is a rapid heartbeat that occurs when exposed to external stimuli or against a background of somatic / functional disorders. During pregnancy, too, there is an increased palpitation, and there are reasons for this.

In medicine, a high pulse is defined as a "tachycardia." In this condition, the heart rate is measured above 100 beats / minute.

Some tonometers can automatically determine the pulse rate, but not all have access to such devices. Therefore, to assess heart rate use the old proven method - palpation of the radial artery with further counting the number of strokes for 1 minute.

Cardiovascular system during pregnancy

Pregnant women undergo a complex adaptation of the body, including the cardiovascular system, which is necessary to protect normal physiological functioning, meet increased metabolic needs and promote growth / development of the fetus. In addition to an increased heart rate, the heart pumps more blood throughout the body at every contraction.

Pulse during pregnancy in trimester

  • First trimester

In normal, uncomplicated pregnancy, the heart rate at rest increases by 15-20 beats per minute, that is, it can be 105-110 beats / min. As with all major systems, cardiovascular changes occurring during pregnancy are controlled by hormones. In particular, the level of progesterone and estrogen increases, which prevent premature contraction of the uterus and expulsion of the fetus. Changes in the heart rate can begin in the first trimester of pregnancy.

  • Second trimester

During this period, there is a general relaxation of smooth muscles along with the expansion of the arteries. This change helps increase the volume of circulating blood while maintaining normal blood pressure. There is an increase in heart rate, the peak of which is reached in the second trimester.

By the fourth month of pregnancy, cardiac output (the amount of blood that the heart pumps) is increased by 30-50%. At this point, the pregnant woman may have health problems, especially if previously observed latent or sluggish current cardiovascular disorders.

  • Third trimester

The period of maximum cardiac output growth falls on 28-35 weeks of pregnancy. By the end of the third trimester, after about 40 weeks, the volume of circulating blood increases by 40% -90% relative to the initial level, which leads to an increase in the heart rate, which means a high heart rate.

The work of the heart now depends on a rather large amount of blood, which allows to ensure adequate delivery of oxygen and nutrients to both the mother and the baby. In the third trimester, these changes are critical to meeting the needs of a fast growing fetus, as well as to prepare a woman for the upcoming work. During childbirth, the heart rate increases dramatically, especially during labor and in response to painful sensations.

Causes

As mentioned above, during pregnancy, even without any complications, the heart rate increases. But there are factors of influence that contribute to the withdrawal of the pregnant woman from equilibrium.

  • A woman often suffers physical or emotional stress.
  • Fast and excessive weight gain during pregnancy.
  • Lying in a horizontal position, especially on the back, for a long time.
  • The lack of vitamins and trace elements, necessary for normal growth of the fetus and the mother's well-being.
  • Smoking and drinking alcohol, including energy and tonic drinks.
  • Lung diseases, especially in the case of development of emphysema or chronic obstructive disease.
  • Exacerbation of chronic tachycardia or another form of arrhythmia, which could be determined before pregnancy.
  • Excessive activity of the thyroid gland, which secretes hormones that affect the work of the heart.
  • Taking medications that affect the heart rate.
  • Heart defects, in which healthy parts of the heart begin to work more intensively due to the weakening of other parts of the myocardium.
  • Improper eating, associated with frequent overeating and consumption of fatty and salty foods.
  • Anemia, especially with very low hemoglobin.
  • Diseases of viral and infectious origin, accompanied by a high temperature reaction.
  • Arterial hypertension.
  • Pericarditis (inflammation of the pericardium), etc.

When determining any pathological effect, it is possible to restore the state of health of a pregnant woman as much as possible to effectively eliminate it.

Symptoms

More often than not, patients with high pulse feel that an "anvil" is working in the heart area or the heart itself is just ready to "jump out" from the chest.

A pregnant woman may experience nausea, and with severe manifestations of tachycardia, a vomitive reflex. If such symptoms are observed, then it is necessary to notify your obstetrician-gynecologist, who will help to establish the source of the pathological condition. One of these reasons can be cardiac pathology, which requires accuracy in diagnosis and drug therapy.

The future mother may feel a muffled or otherwise distinct pulsation in the abdomen, most often in its lower part. The first source of pulsation can be the hiccup of the fetus, and the second - the movement of plasma along the aorta. Such a symptomatology can develop on any week of pregnancy. If the high pulse is not accompanied by symptoms of pain and other unsafe manifestations, one should not worry.

If a pregnant woman is diagnosed with dizziness, accompanied by a decrease in the general tone of the body, low blood pressure and periodic loss of consciousness, it is necessary to immediately seek medical help to normalize the condition.

Sometimes, against a background of tachycardia, a woman begins to feel a lack of air, which indicates the development of hypoxia. In this case, the pregnant woman breathes intensively, because protective reactions are included to provide the child with the necessary amount of oxygen. In this situation, the cause of the increased heart rate should be established.

A rapid heartbeat can be accompanied by a headache. This may be the first symptoms of hypotension.

Diagnostics

A healthy heart during a normal emotional state works at a speed of 60-80 beats per minute. Such a reduction regime allows to provide the human body with enough oxygen and substances necessary for normal work: vitamins and trace elements.

During pregnancy, the volume of circulating blood that serves both the fetus and the body of a woman increases.Accordingly, in pregnant women the number of strokes can increase to hundreds, and in some cases up to 115 beats / min. Such an increase in the doctors' indices is called physiological tachycardia.

Diagnosis of high heart rate during pregnancy does not require additional equipment. This procedure is carried out at each meeting of the pregnant woman with a doctor (whether therapist, cardiologist or obstetrician-gynecologist). If necessary, you can manage the heart rate at home. To make such a measurement is not difficult, you just need to know the pulse counting algorithm:

  • The best place to count the heart rate is a carotid artery on the front of the neck or a radial artery on the wrist of one of the arms.
  • The index and middle fingers of the opposite hand establish the location of the pulsation of the vessel and calculate the number of rhythmic beats determined within one minute.
  • The procedure should be carried out only at rest, preferably after rest or complete tranquility of the pregnant woman.There is no need to do the calculations after taking fat-saturated food.

In addition, with the help of an electrocardiogram (ECG), the number of beats per minute is most accurately diagnosed.If the doctor has a suspicion about the presence of any heart disease, he directs the pregnant woman to further research. Such methods can be heart ultrasound or holter monitoring (conducted for 24 hours to fix the heart rate and further analysis of the data).

The heart rate can be measured with a modern electronic tonometer, which can be purchased at any pharmacy.

If no significant abnormalities and abnormalities are observed, the woman quite successfully gives birth in a natural way.Some pathological changes in the heart, which lead to an increase in the heart rate, may be an indication for caesarean section. In this case, the obstetrician-gynecologist together with the cardiologist makes the supposed tactics of conducting labor.

Treatment

Most often, a high pulse in a pregnant woman does not cause serious concern, since this physiological reaction makes it possible to provide the fetus with everything necessary. However, when determining a high pulse, in conjunction with adverse clinical symptoms, it may be necessary to have a medical consultation and special treatment.

There are various tactics for treating a high pulse in pregnancy, which depend on the cause of the development of the disorder:

1. When a tachycardia occurs against a background of emotional overstrain, doctors usually recommend that you take a soothing tea (from baldness, motherwort, mint, valerian) and relax as much as possible, thinking about the pleasant and positive moments of life. If necessary, a drug can be administered according to the type of Persene.

Persen is a medicine that doctors consider relatively safe for the fetus. The composition of the drug includes: lemon balm and mint leaves, as well as valerian root extract. At pregnancy the preparation is appointed only by the doctor, therefore the self-treatment is inadmissible. After entering the drug in the protocol of therapy, his admission is strictly controlled by a doctor. Any medicine during pregnancy is prescribed only in an emergency situation.

2. With intensive excitation, valokordin can be prescribed from the medications, which helps to reduce the heart rate. It is not recommended to use the drug in case of individual intolerance to the pregnant woman of any of its components, as well as in case of liver and / or kidney dysfunction.

3. If the pathology takes a heavy course, then the decision to treat a pregnant woman is established at a medical consultation, which includes various specialists. Obstetrician-gynecologist, cardiologist together with other doctors make up a protocol of therapy that should maximize the woman's health, while danger for the child should be minimized.

Prevention

In most cases, to prevent this problem or at least reduce the intensity of its expression, you can adhere to simple rules.Preventing high heart rate during pregnancy includes the following recommendations.

  • Exclude or significantly limit the use of tonic drinks (strong tea and coffee).
  • Try to get rid of bad habits (smoking and drinking alcohol).
  • Practicing a healthy lifestyle: do not overload yourself with unnecessary work, rest more, but constantly lying on the couch is not worth it, because pregnancy is not a disease, so you do not need to comply with bed rest.
  • Do not take the medication yourself, and it is also very cautious to administer new medications prescribed by the doctor.
  • Try to avoid stressful situations, adjusting your emotional background to match positive emotions.
  • Minimize the reception of power engineers, chocolate.
  • Relax in combination with walking in the fresh air.
  • Living quarters should often be ventilated so that you can breathe clean air.
  • Limit consumption of fatty and salty foods. Food should be balanced and rich in vitamins and trace elements.
  • Should be eaten in small, small portions, not allowing overeating.
  • Easy gymnastics for pregnant women will only benefit.
  • If the pulse starts to increase, you need to drink a glass of clean water in small sips, and then lie down and relax.
  • To calm down, you can make several deep exhalations and breaths - such a breathing exercise will be useful.
  • It's important to keep track of your weight. Its excessive increase can trigger a rapid heart rate.

If the methods presented could not prevent the problem, you should consult your doctor, especially if other pathological symptoms appear.

Forecast

A high pulse during pregnancy is unpleasant, but more often than not a dangerous symptomatology. A slightly increased pulse is a natural physiologically grounded process that occurs during pregnancy. In this regard, the prognosis of high heart rate during pregnancy is most often given favorable. After childbirth, this problem, as a rule, goes away by itself, you only need to follow the recommendations outlined above. In the case of a more severe pathology, the prognosis is good, it is only necessary to eliminate the source of the high pulse, and the symptomatology will disappear.

The waiting time of the child is a wonderful period in the life of every woman, so I very much want it not to be overshadowed by various uncomfortable sensations and worsening of the general condition. Therefore, in order to prevent or minimize manifestations, when there is a high pulse during pregnancy, all the recommendations voiced by the attending physician should be followed. In case of an exacerbation of symptoms, it is important to immediately seek help from a specialist.
