Tachycardia in pregnancy

Tachycardia in pregnancy


Tachycardia is a medical condition characterized by accelerating heartbeat at over 90 beats per minute. Although it is natural for the heart rate to increase slightly, doctors say tachycardia occurs when the heartbeat of the pregnant woman exceeds 100 beats per minute.

Causes of tachycardia in pregnancy

The increase in the number of heart beats per minute above the normal average can be influenced by several factors, which help doctors establish the therapeutic regimen needed to rebalance the heart rate:

  • anemia;
  • allergies to prenatal vitamins;
  • obesity;
  • asthma;
  • pulmonary embolism;
  • thyroid problems;
  • ectopic pregnancy;
  • pulmonary infections;
  • fever;
  • dehydration;
  • uterine rupture;
  • anxiety or stress;
  • side effects of medicines;
  • cardiovascular diseases;
  • embolism with amniotic fluid etc.

Symptoms of tachycardia in pregnancy

Pregnancy tachycardia is accompanied by a series of symptoms based on which you should go to the doctor to receive the related therapeutic measures:

  • palpitations;
  • chest pains;
  • increased fatigue or feeling tired;
  • breathing difficulties;
  • faintness;
  • damping the various parts of the body, etc.

Risks or complications of tachycardia in pregnancy

Left untreated, tachycardia raises a lot of health problems and can put both your pregnancy and your life in danger. In the case of tachycardia, there is a risk that the fetus will not receive enough oxygen and nutrients.

The increased heart rate causes the pregnant heart to stop pulsing enough blood in the body and the nutrients to reach the fetus. In this case, the intrauterine development of the baby is compromised and there is a risk of labor and premature birth.

Even if the pregnancy is completed, specialists say that labor and birth are difficult due to the increased heart rate, which may require emergency caesarean section. The risk of heart attack or death is increased in the case of tachycardia, if the condition was caused by a secondary heart condition.

Tachycardia causes increased blood pressure and puts pressure on the heart, which is already overloaded due to pregnancy.

Treatment of tachycardia in pregnant women

Establishing treatment to adjust heart rate depends on the causes that led to the appearance of tachycardia. Doctors first investigate the causes and determine if the accelerated heart rate has appeared on the physiological or pathological background.

If it has appeared on the physiological background, due to eating habits, medications or stress, doctors recommend avoiding pulse-boosting food incentives - beverages and caffeine foods - replacing drugs that could have a side effect - but also relaxation meant to relieve anxiety.

In the case in which the tachycardia appeared on the pathological background, due to a secondary disease, the doctors will establish a suitable treatment for its control until the end of pregnancy. Treatments commonly used to combat tachycardia include beta blockers, antiarrhythmic drugs or calcium channel blockers, but doctors advise pregnant women to take medicines only at the doctor's recommendation, in order not to endanger their pregnancy.
