If you exercised regularly before pregnancy, there's no need to focus on your heart rate for exercise during pregnancy.

You can even see and measure this flicker of light on an ultrasound. The beats per minute (bpm) start at a slow 90 to 110 bpm and increase daily. They continue to increase until they peak around week 9, between 140 and 170 bpm for boys and girls alike.

The mean basal heart rate of 148 bpm at a median gestation of 161 days (23 weeks) is within the 110-160 bpm normal range for viable fetusses (11). The finding of more accelerations than decelerations is in contrast to previous reports based on ultrasound recordings at this gestational age.

In pregnancy, heart rate (HR) increases by 25%; thus sinus tachycardia, particularly in the third trimester, is not uncommon. Ectopic beats and non‐sustained arrhythmia are encountered in more than 50% of pregnant women investigated for palpitations while sustained tachycardias are less common at around 2–3/1000.
