ECMO may be used, for example, to treat ARDS (acute respiratory distress syndrome), lethal smoke inhalation injury, or irreversible heart failure. As a general rule, ECMO is only used for limited time because of the high risks of bleeding, clotting, infection and organ failure.

Extrasystole
A premature contraction of the heart that is independent of the normal rhythm of the heart and that arises in response to an impulse in some part of the heart other than the normal impulse from the sinoatrial (SA) node. The extrasystole is followed by a pause, as the heart electrical system "resets" itself and the contraction following the pause is usually more forceful than normal. These more forceful contractions are frequently perceived as palpitations.
Extrauterine
Outside the uterus (the womb). As opposed to intrauterine: inside the uterus. For example, normal pregnancies are intrauterine; extrauterine pregnancies can occur in the uterine tube or abdominal cavity and are distinctly abnormal.
Extrauterine pregnancy
A pregnancy that is not in the usual place and is located outside the inner lining of the uterus. A fertilized egg settles and grows in any location other than the inner lining of the uterus. The large majority (95%) of extrauterine pregnancies occur in the Fallopian tube. However, they can occur in other locations, such as the ovary, cervix, and abdominal cavity.

PREVIOUS AND NEXT TERMS--------------------------------------
Epigenesis
Originally from the Greek "epi" (on, upon, on top of) and "genesis" (origin); the theory that the embryo is not preformed in the ovum or the sperm, but that it develops gradually by the successive formation of new parts. The concept has been extended to other areas of medicine, with different shades of meaning. Some of the other meanings are as follows: 1. Any change in an organism that is due to outside influences rather than to genetically determined ones. 2. The occurrence of secondary symptoms as a result of disease. 3. Developmental factors, and specifically the gene-environment interactions, that contribute to development. 4. The appearance of new functions that are not predictable on the basis of knowledge of the part-processes that have been combined. 5. The appearance of specific features at each stage of development, such as the different goals and risks that Erikson described for the eight stages of human life (trust vs. mistrust, autonomy vs. doubt, etc.). The life cycle theory adheres to the epigenetic principle in that each stage of development is characterized by crises or challenges that must be satisfactorily resolved if development is to proceed normally.
