A heart rate over 140 beats per minute during pregnancy can be a sign of several conditions, ranging from benign causes like anxiety or dehydration to more serious issues such as hyperthyroidism, infection, or preeclampsia. It's crucial to contact your doctor or midwife immediately if you experience this, as prompt evaluation and treatment are necessary to ensure the well-being of both mother and baby. The underlying cause needs to be identified and addressed to prevent potential complications.

A heart rate over 140 beats per minute during pregnancy can be a cause for concern and requires immediate medical attention. While a slightly elevated heart rate is normal during pregnancy due to increased blood volume and metabolic demands, a rate consistently above 140 bpm could indicate several potential problems, including:

• Dehydration: This is a common cause and often easily remedied.
• Infection: A fever from an infection can significantly raise the heart rate.
• Hyperthyroidism: An overactive thyroid gland can increase metabolic rate and heart rate.
• Anemia: Low red blood cell count can lead to increased heart rate.
• Cardiac conditions: Pre-existing or pregnancy-related heart conditions.
• Preeclampsia or other pregnancy complications: These conditions can stress the cardiovascular system.
• Anxiety or panic attack: Stress can also elevate heart rate.

It's crucial not to self-diagnose. If your heart rate is consistently above 140 bpm during pregnancy, you should contact your doctor or midwife immediately. They can determine the cause and recommend appropriate treatment.
