Why is my heart beating so fast 20 weeks pregnant?

Because your body has extra blood, the heart has to pump faster to move this blood through. Your heart rate may increase by 10 to 20 extra beats per minute. In the second trimester, blood vessels in your body start to dilate or get bigger.

What is a high heart rate when pregnant?

During pregnancy, the amount of blood pumped by the heart (cardiac output) increases by 30 to 50%. As cardiac output increases, the heart rate at rest speeds up from a normal prepregnancy rate of about 70 beats per minute to as high as 90 beats per minute.

What is a normal heartbeat at 20 weeks?

By 20 weeks the average (SD) fetal heart rate is 140 (20) bpm with a gradual decrease to 130 (20) bpm by term. In the healthy fetus the heart rate is regular, usually remains between 110 and 180 bpm, and has a beat‐to‐beat variation of 5–15 bpm.

What causes high fetal heart rate second trimester?

During the second trimester, the baby’s heart may begin to beat irregularly as the electrical pathways of the heart mature. This is natural, and not a cause for alarm unless the irregularity lasts for a considerable period of time.

When does the heart rate start to increase during pregnancy?

The heart rate starts to increase from the 7th week, and it peaks by 10 – 20% by the third trimester.

Is Fast Heartbeat During Pregnancy Harmful?

What should your heart rate be at 10 weeks?

The study also found that the average heart rate rises steadily through pregnancy. At 10 weeks, the average heart rate was 79.3 BPM. By 40 weeks, the average rate was 86.9 BPM. A person’s heart rate during pregnancy may be higher or lower than these figures if their prepregnancy heart rate is higher or lower.
