Premature atrial complexes are caused by abnormal electrical impulses transmitted by the atria (either of the upper chambers of the heart). The abnormal electrical impulses cause contractions of the upper chamber of the heart earlier than expected. Such premature beats are generally harmless. slide 1 of 7.
A large uterus or a short cervix can cause you to go into labor early. A chronic illness , such as high blood pressure, diabetes, or obesity, can cause early labor. An infection , such as a urinary tract infection or vaginal infection, can weaken the membranes (linings) of the amniotic sac around your baby. This could lead to premature rupture of the membranes and preterm labor. Problems with the placenta , such as placenta previa or placental separation, may cause preterm labor.
