title: Working hypothesis relative to the hemodynamics of menstruation and pregnancy.
abstract: A working hypothesis relative to detailed hemodynamic changes that occur during menstruation and pregnancy theorizes that the marked biophysical similarities existing between the postovulatory phase of the menstrual cycle and the latter half of pregnancy are endocrine based. The data are acquired with apparatus that records cutaneous pressure pulses and the maternal electrocardiogram, which together provide the basis for deriving the determinants of mean arterial pressure.
