What happens to pregnant women's electrocardiogram and sinus tachycardia

Sinus tachycardia in pregnant women may be caused by emotional excitement, fever, anemia and other reasons.

1. Emotional excitement in pregnant

women can lead to sympathetic nerve excitation, release adrenaline, which can act on the myocardium, causing myocardial contractility to strengthen, heart rate to accelerate, sinus tachycardia.

2. During fever

and fever, metabolism is strong, heat is emitted more, oxygen consumption of the human body increases, and the heart appears compensatory acceleration in order to meet the needs of physiological functions, resulting in sinus tachycardia.

3. Anemia

Due to insufficient blood oxygen, the heart needs to pump more oxygenated blood to maintain physiological activities, so the heart load increases, which will lead to accelerated heartbeat and cause sinus tachycardia.
