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.
The data in the graph above shows that: 1  Women under 35 have the highest success rates in all of the egg number groups. 2  Women under 38 in our IVF program have acceptable live birth rates even with only 3 - 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs. Women under 38 in our IVF program have acceptable live birth rates even with only 3 - 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs. 2  Women 38-40 and 41-42 years old have low live birth rates with low egg numbers. 3  Success rates are much better when relatively high egg numbers are obtained.
