But, sometimes your heart gets out of rhythm. An irregular or abnormal heartbeat is called an arrhythmia. An arrhythmia (also called a dysrhythmia) can involve a change in the rhythm, producing an uneven heartbeat, or a change in the rate, causing a very slow or very fast heartbeat.
The placenta is an organ that provides nutrients to your baby while youâre pregnant. Its typical location is in the upper part of the uterus, and it normally detaches from the uterine wall after you deliver your baby. However, in the case of placental abruption, the placenta detaches too early. This can cause complications, because your baby may not get enough oxygen or nutrients. You can also experience bleeding thatâs harmful to you and your baby.
The placenta is said to be retained when it is not expelled from the uterus even 30 minutes after the delivery of the baby. Normally the placenta is expelled in three stage-it first separates from the uterine muscle, then it descends into the lower segment of the uterus and vagina and then it is expelled outside.
