Introduction
Will a maternal heart rate of 105 beats per minute cause fetal hypoxia? Analysis based on symptoms: If there are no obvious symptoms such as palpitations or shortness of breath, and the fetal heart rate is within the normal range, the fetus generally will not experience hypoxia. However, if symptoms such as palpitations, anxiety, shortness of breath, or difficulty breathing are present, this may affect blood supply to the fetus and lead to fetal hypoxia.

Fetal hypoxia due to a maternal heart rate of 105 beats per minute needs to be analyzed based on individual symptoms. The specific analysis is as follows:

1. No effect

A pregnant woman's normal heart rate typically ranges from 60 to 100 beats per minute. If the heart rate is 105 beats per minute but there are no obvious symptoms such as palpitations or anxiety, and the fetal heart rate remains normal, fetal hypoxia generally will not occur.

2. Possible effect

If a pregnant woman has a heart rate of 105 beats per minute accompanied by symptoms such as palpitations, anxiety, shortness of breath, or difficulty breathing, this may indicate reduced effective cardiac output, affecting the heart's contraction and relaxation and leading to inadequate organ perfusion. Under these circumstances, blood supply to the fetus might be compromised, potentially causing fetal hypoxia.

Pregnant women with a heart rate of 105 beats per minute are advised to visit a hospital for comprehensive evaluations including electrocardiogram (ECG), echocardiography, and blood tests such as complete blood count, thyroid function, electrolytes, liver function, and other relevant examinations to determine the underlying cause.
