Question: is tachycardia dangerous in pregnancy?
Answer: 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.
