The dobutamine stress echo test involves the injection of a medication called dobutamine while you are closely monitored. The medication stimulates your heart in a similar way as exercise. Important: If you have a pacemaker/defibrillator, it must be checked at Cleveland Clinic before your dobutamine stress echo test.
Your Baby During the Second Trimester. The second trimester is normally considered to be from the beginning of the fourth month to the end of the sixth month. This works out in weeks to start from about the thirteenth week of pregnancy.
The second trimester includes weeks 14 through 27, and the third trimester begins at week 28 and extends until the pregnancy is expected to end at 40 weeks. During the 40 weeks of pregnancy, the woman may be referred to as a gravida, the Latin term for a pregnant woman. If it is her first pregnancy, she is a primigravida; if she has had other births, she is a multigravida. The word para refers to the parting of mother and baby, or the birth itself.
