Pregnant women heart rate irregular, myocardial ischemia on the fetus has an impact?

Pregnant women with irregular heart rate, myocardial ischemia has an impact on the fetus, should be analyzed as appropriate:

if the pregnant woman has transient myocardial ischemia, there is simple, mild sinus arrhythmia, and no obvious symptoms, in addition, there is no organic heart disease or other diseases, can eliminate the inducing factors, generally for the fetus has no obvious impact. If the pregnant woman repeatedly and continuously has myocardial ischemia, there is a serious arrhythmia, and because of the decline in heart function, resulting in reduced pumping blood, unable to meet the needs of fetal blood supply, it will affect the growth and development of the fetus.
