Tachycardia During Pregnancy
Tachycardia during pregnancy refers to the condition of having a heart rate above ‘normal.’ A heart rate above 100 beats per minute (BPM) during pregnancy is termed as tachycardia. Since a pregnant woman’s heart works harder than normal, the heart rate increases by 10-20 beats per minute, thus causing palpitations in many women during pregnancy. Think about it, and an increased heart rate is actually perfectly natural during the term. The symptoms of tachycardia during pregnancy include chest pain, shortness of breath, dizziness, and fatigue. In difficult situations, the pregnant mother may faint or experience numbness.

What Causes Tachycardia During Pregnancy?

Tachycardia during pregnancy mean. Your body does not have to support the heartbeat of a fetus normally! Your body never has to go through such extreme stress as you do while carrying your baby. In the 40 weeks of pregnancy, hormones, bodily changes, new cells, a growing uterus and baby, a woman’s heart has to work harder and thus can be stressed. The following reasons justify why there is absolutely no need to panic on experiencing a slightly ‘above the limit’ heartbeat. Doctors usually classify the normal condition under gestational Supra-Ventricular Tachycardia (SVT)
1.Major Causes Of Tachycardia

  • Stress, anxiety, and fear: Hormonal changes, expanding uterus, growing baby, increase in blood vessels, and other changes in the body cause stress to the heart and can cause tachycardia during pregnancy. Expectant mothers also quite naturally feel a constant sense of dread about the safety of the baby and herself. The psychological tumult can definitely manifest as panic attacks and anxiety
  • Overworking heart: Your body has to adapt to various changes demanding an increased output from the heart. Besides setting the heartbeat of your growing fetus, your heart also has to meet with the needs of replenishing the changing body

2.Other causes of tachycardia include:

  • Excessive blood use and expansion of organs within the body
  • You grow a placenta in the uterus to offer a safe cushion for the baby. It is essentially a special tissue mass with a deep network of blood vessels and hence puts extra pressure on the heart
  • Your uterus also grows to its optimum limits, and the body must support this expansion
  • Your breasts also become fuller in anticipation of the baby’s arrival. The rapid proliferation of blood vessels in your bosom needs a constant boost from the heart as well
  • Diseases like thyroid and anemia also put you at the risk of tachycardia during pregnancy
  • In addition, the hormonal changes, side effects of pregnancy medications, and excessive weight gain also exert extra stress on your circulatory system.
  • Cigarette smoking and alcoholism and excessive caffeine as being stimulants, they can increase the heart rate if consumed in excess

Tachycardia for pregnant women

Types Of Tachycardia

Tachycardia for pregnant women can be quite a normal condition, and there are different types of tachycardia referring to the place they are coming from it. Sinus tachycardia during pregnancy occurs when the higher rate beat originates from the sinus node, commonly known as the heart’s natural pacemaker. Sinus tachycardia can be appropriate or inappropriate and is quite common in pregnant women. Non-sinus tachycardia originates in the chambers of the heart. It is divided as supraventricular (tachycardia during pregnancy that originates from the upper chambers of the heart) and ventricular (tachycardia that originates from the lower chambers of the heart). Though sinus tachycardia is more common, yet it is imperative to get yourself diagnosed by your doctor.

Symptoms of Tachycardia In Pregnant Women

Palpitations, chest pain, breathlessness, fatigue, etc. are some common indicators that your heart is beating faster. A high heart rate in pregnancy can also cause the woman to faint, feel dizzy, making her extensively anxious. Some women, in severe cases, also become intolerant to everything.

Treating Tachycardia During Pregnancy

As mentioned above, the bouts of palpitation often subside by themselves. However, please do not hesitate to contact the doctor any time you want. Nevertheless, you should recognize the supernatural stress your body undertakes and allow yourself the time to settle. If it is about an emotional disturbance, try to calm yourself. An occasional cup of Chamomile tea can do wonders! Be careful not to overuse the tea, though. Keep it in limits. Pregnant women should avoid stimulants and keep themselves emotionally and physically healthy by resting plenty, drinking lots of water and other healthy liquids to keep the body cool and well hydrated. These simple things will keep anxiety at bay, keeping your body the ability to cope with increasing heart rate.
You can also check out the yogic positions that you can try during pregnancy. Other forms of meditation should also help. In fact, sex during pregnancy with a loving, caring partner can help you deal with the anxiety! Do not overuse this approach, though. Most importantly, abstain from coffee, alcohol, and tobacco or other nerve stimulants. You will have a lot to celebrate after the delivery!
Nevertheless, some rare conditions of tachycardia do require significant attention. For example, the onset of palpitations may coincide with heavy bleeding a few days ago. Now, do note that some bleeding during pregnancy is not unusual. Maybe you are experiencing an increased heart rate only because you are afraid of all that blood. However, if you have had, unfortunately, received a severe injury, make a fast appointment with the doctor.

Medical Intervention For Tachycardia

Please understand that pregnancy is the most extensive responsibility undertaken by a human body. It is complex, not fully understood yet, and the conditions vary uniquely from one woman to another. You can definitely consult the doctor if your tachycardia is explainable by any of the above terms. However, a good gynecologist will assure you that there is nothing to worry at all. In fact, tests show the baby’s heart rate to be completely normal even when the mother is experiencing an increased heartbeat. Most of the time, the palpitations soon cease by themselves, and you find relief. Never take OTC medications on your own. Some of these OTC drugs can cause birth defects in the fetus.

Serious Complications Of Tachycardia

All other serious complications such as ectopic pregnancy, amniotic fluid embolism, placental abruption, miscarriage, uterine rupture, and pulmonary embolism are associated with tachycardia during pregnancy. In fact, an overdose or allergic reaction to prenatal vitamins can also induce stress on the heart. Underlying lung and heart conditions can also become conspicuous during the term. The doctor will do her best to ensure the safety of the mother and the baby, under the unique conditions of the patient.

Medications For Tachycardia

Yes, there are medications for tachycardia. However, do remember that pills are drugs – and may not be safe for you or your baby. Do not simply buy medicines over the counter! The common anti-arrhythmic drug Amiodarone has been shown to cause fetal abnormalities. Beta or calcium channel blockers or anti-arrhythmic medications are usually prescribed for treating sinus tachycardia. Most cases of Supraventricular tachycardia seen during pregnancy are harmless and may not need any treatment. It is very important to get yourself properly checked by the doctor and never, ever self medicate. In fact, the racing heart rate may develop as a side effect of medications such as pseudoephedrine. Always consult the doctor, but take several opinions. Check online forums to find the experience of other expectant women. A good doctor will take the best efforts to alleviate your concerns.
