About Transcutaneous Pacing. Transcutaneous pacing is the technique of electrically. stimulating the heart externally by using a set of electrode pads. This technique is not as efficient as transvenous pacing. because the electrical stimulus (the pads) is not in direct contact. with the heart muscle. Transcutaneous pacing is a good. temporary solution in an emergency situation to improve a slow. heart rate resulting in inadequate cardiac output.
Most clinics have a certain upper age limit after which they will not perform in vitro fertilization (IVF) with the woman's own eggs. In the United States, the age limit is somewhere between 42 and 45 in most programs. Most IVF clinics allow the patient to be a recipient of donor eggs through to about age 50. When donor eggs are being used, the age of the egg donor is the important issue.
A new study of 101 women age 50 and older who had children using donated eggs reveals that pregnancy at this age carries about the same risks as similarly induced pregnancies in younger women.
