Pregnancy brings numerous changes that expectant mothers may not always anticipate. One such change is an increased heart rate. But is a faster heartbeat during pregnancy a cause for concern, and can this condition be prevented? Read on to learn more.

How Pregnancy Affects the Heart

During pregnancy, a mother’s body requires additional blood to support fetal development. By the second trimester, blood vessels begin to expand to accommodate increased circulation to both the mother’s body and the fetus. This adjustment often results in a slight drop in blood pressure.

As the pregnancy progresses into the final trimester, approximately 20% of the mother's total blood volume is directed toward the fetus. To ensure efficient circulation, the heart must pump more rapidly, leading to an increased heart rate of about 10-20 additional beats per minute.

This rise in blood volume can cause the heart rate to accelerate by up to 25% compared to pre-pregnancy levels. Some women may also notice occasional slow beats, skipped beats, or an irregular heartbeat.

While heart palpitations during pregnancy are usually normal and not a cause for alarm, they can sometimes signal an underlying heart condition. If an increased heart rate is accompanied by symptoms such as dizziness, sweating, or difficulty focusing, it’s important to consult a doctor.

What Causes Heart Palpitations During Pregnancy?

In most cases, heart palpitations occur due to the body's natural response to increased blood volume and circulation demands during pregnancy. However, several other factors can contribute to this condition, including:

• Stress or anxiety
• Caffeine consumption
• Medications containing pseudoephedrine
• Heart complications from a previous pregnancy
• A history of heart disease, such as coronary artery disease or pulmonary hypertension
• Thyroid disorders
• Anemia
• Dehydration
• Low blood sugar levels

During routine prenatal check-ups, it’s important to inform your doctor about any heart palpitations you experience. A medical evaluation will help determine whether the condition is normal or requires further assessment.

Managing Heart Palpitations During Pregnancy

If your heart palpitations are not linked to an underlying health issue and are not accompanied by concerning symptoms, your doctor may not recommend any specific treatment. Typically, heart rate fluctuations resolve on their own after childbirth.

However, there are several ways to help manage a racing heartbeat during pregnancy:

Stay hydrated

Dehydration can contribute to heart palpitations. Increasing water intake can help prevent dehydration and support overall fetal health.

Avoid smoking and alcohol

Tobacco and alcohol can interfere with circulation and heart function, further increasing heart rate. If you are pregnant and still engaging in these habits, it’s important to stop immediately, as both substances can negatively affect fetal development.

Limit caffeine, salt, and sugary foods

Caffeinated products such as coffee and chocolate can exacerbate heart palpitations. To minimize this risk, consider reducing caffeine and sugar intake. Additionally, pregnant women are advised to avoid excessive salt and unhealthy fats.

If heart palpitations are caused by an underlying medical condition, your doctor may conduct further tests to determine the most suitable treatment plan. In some cases, medications or procedures such as cardioversion may be recommended to help regulate heart rhythm.

Heart palpitations during pregnancy are generally considered normal and harmless. However, if they are accompanied by symptoms such as dizziness or difficulty concentrating, it’s best to seek medical advice. You can also access pregnancy-related consultations through the Ai Care application, available on the Play Store and App Store.
