Described herein are systems, devices, and methods for non-invasive pregnancy testing. The systems, devices, and methods can be used to provide pregnancy status information of a subject by detecting cardiovascular activity of a fetus in the subject. Subjects can include ruminants, ungulates, and humans.

Maternal and fetal heart rate monitor

The present disclosure describes systems, methods, and devices to infer changes in pulmonary artery pressure in a subject using Doppler radar. A portable, non-invasive device for non-invasively measuring right ventricular cardiac motion that can be used in a subject's home can infer pulmonary artery pressure changes to increase patient compliance and mitigate the likelihood of heart decompensation. A mobile pulmonary artery pressure monitor can be especially useful to patients with congestive heart failure who are elderly, incapacitated, or do not have easy access to a clinic, doctor's office, or hospital.
