Causes of sinus arrhythmia in pregnant women

Sinus arrhythmia in pregnant women may be related to fetal oppression, bad living habits, diseases and other factors.

1. Fetal oppression

With the increase of fetal size, maternal organs and tissues are oppressed, resulting in increased resistance of blood vessels, which may cause reduced blood flow to the heart and cause sinus arrhythmia.

2. Bad living habits When pregnant

women stay up late or drink strong tea or coffee, it may increase sympathetic nerve excitability, resulting in increased cardiac contractility and increased cardiac load, thus causing sinus arrhythmia.

3. Diseases

Anemia during pregnancy, organic heart diseases, hyperthyroidism, pregnancy hypertension and other diseases will cause sinus arrhythmia due to increased cardiac load.
