An apparatus (100) to test for orthostatic hypotension, comprising an input device (106), a memory (104), a processor (102), and an output device (108). The input device (106) is configured to receive time information related to an occurrence time of at least one lying-down event and an occurrence time of at least one standing-up event of a subject to be tested, whereby the lying-down and standing-up events are alternately occurring. The memory (104) is configured to store a program. The processor (102) is configured to run the program. When run in the processor (102), the program is configured to execute the following operations: acquiring an initial parameter of an object to be tested, the initial parameter comprising a blood flow characteristic parameter of the subject to be tested throughout an entire testing period determining a lying-down period parameter during the occurrence of each lying-down event and a standing-up period parameter during the occurrence of each standing-up event analyzing all lying-down period parameters and all standing-up period parameters using a trained classifier, so as to determine a likelihood that the subject to be tested has orthostatic hypotension. The output device is configured to output feedback information about the likelihood of orthostatic hypotension. The apparatus (100) for testing orthostatic hypotension can autonomously test for orthostatic hypotension.La présente invention concerne un appareil (100) permettant de vérifier la présence dune hypotension orthostatique, comprenant un dispositif dentrée (106), une mémoire (104), un processeur (102) et un dispositif de sortie (108). Le dispositif dentrée (106) est configuré pour recevoir des informations temporelles relatives à un moment dapparition dau moins un événement de passage en position couchée et à un moment dapparition dau moins un événement de passage en position debout dun sujet à tester, les événements de passage en position couchée et de passage en position debo
