ECG and one electrode, a respiration sensor, which is mounted on the tubular body for monitoring breathing at least is arranged outside the tubular body in order to monitor the tubular body, the ECG signal of the testee for holding the tubular body , a state in which is mounted on the tubular body in order to limit the passage selectively, the first configuration is not restricted, and the sealing mechanism is in a restricted state, the second configuration given in the inside of the tubular body and a pressure monitoring device mounted on the tubular body in order to check the pressure, is a cardiovascular autonomic neuropathy testing device versatile disposable, when it is in the first configuration (i) sealing mechanism, the apparatus may be used to perform a metronome breath test, when in the second configuration is (ii) sealing mechanism, the apparatus may be used to perform the Valsalva maneuver testing, (iii) sealing mechanism is either When in Kano configuration, the apparatus can be used to perform the HRV standing tests.
