The authors present seven pregnant patients with Rh immunisation. Four of them were of mild degree and three were severely inmunised. All of them had an exercise tolerance test as well as an oxytocin test to evaluate the fetal response to maternal exercise and uterine contractility. The classification utilized for evaluating the fetal response to exercise and its clinical implications are presented. It is concluded that the exercise test is of diagnostic and prognostic value regarding chronic distress during pregnancy and the oxytocin test may help to decide wether the fetus will tolerate the uterine contractions of parturition, and if surgical intervention might be contemplated if during a monitorized labor severe fetal heart changes occur.
