Why postpartum Fluctuation heart

Postpartum heart is the heart after delivery of abnormal phenomena, such as maternal feel nervous, chest tightness, not horizontal, short breath, and so on. Generally 24-28 hours postpartum most obvious. If prenatal maternal have heart disease, heart function is one (that is mild heart disease), a week after will be completely back to normal. Cardiac function belongs to the two (that is, the mild heart attack after labor that is the disease) may change from light weight, punished even heart failure. Which factors lead to changes in maternal heart? This is because pregnancy, with the development of fetal growth, uterine inevitable, and make a diaphragmatic rise to the top of the heart, Heart position has shifted slightly. During pregnancy, cardiac workload gradually increased, slight heart hypertrophy and heart rate. Inspection, the heart can be found widening the boundaries, there may be some extra noise and such. If pregnant women in prenatal make periodic checks, in the custody of doctors, mild heart of pregnant women, generally adapt to this change into labor. But childbirth is the burden of cardiac tests, because labor, Each contraction of the uterus can be 400-500 milliliters of blood discharge from the uterus, into the blood circulation,Increase the burden on the heart. When in maternal fetal forced to make the delivery of breath, increased maternal blood pressure, pulmonary pressure increased recycling, The increase in oxygen consumption without adequate replenishment, then there will be bruising maternal phenomenon. When deliverying the fetus, placenta discharge, uterine suddenly reduced, the original set up and placental blood circulation also suddenly stopped, Then intrauterine blood suddenly entered the mother's blood circulation; In addition, original IVC by uterine suddenly reduce pressure from the inferior vena cava blood upon reflection greatly increased; together with the downward movement of the diaphragm, cardiopulmonary is also the location of IP return to the position before pregnancy, this series of changes, a health fair in the heart of competence, but heart disease often aggravate their condition is the direct cause. If those with mitral stenosis and maternal, may have also caused acute pulmonary edema, suffering from rheumatic heart disease, Congenital heart of maternal postpartum often aggravate their condition, or even the United vegetables to heart failure. Therefore, pregnant women suffering from heart disease, the expected date of one month before hospitalization labor, physicians in the custody of the necessary medications and reasonable guidance. Postpartum observed that the heart needed to restore order discharged.
