The GAT application facilitates several tests:

Valsalva test
Tilt Table test
Deep Breathing test
Stand test
Cold Pressor test
Carotid Sinus Massage test
Drugs Administration test

This procedure list is based on customer feedback from key opinion leaders all over the world.

The GAT application uses a pre-defined protocol. Yet, all test protocols are adjustable. This means that the operator can select which tests should be performed, including test order and frequency. Operators can also modify the test parameters, for example test duration and minimal airway pressure during the Valsalva test, and save these parameters in a custom user profile. Another relevant feature of the GAT application is that markers are automatically added to the measurement during all procedure steps, for example when a new maneuver is being started, executed or finished. These markers and corresponding time points are also included in the GAT report.

Video recording during Tilt Table test

A tablet records a video of the patients’ face during the Tilt Table test. After the test, this video can be synchronized with the measurements for a complete review via the NOVAscope PC application. Video recording is recommended by international autonomic testing guidelines, such as the ESC 2018 Guidelines for the diagnosis and management of syncope. They state: “Adding video recording to a tilt table test permits objective and repeated review of clinical signs in relation to Blood Pressure and Heart Rate, and helps to assess the relative contribution of bradycardia and hypotension to syncope”.

Guidance of the patient during Deep Breathing test

During the Deep Breathing test, the patient can follow the breathing rhythm that is visualized on the tablet. Moreover, it shows the remaining time to inhale and exhale according to the indicated rhythm. These features support a standardized procedure any time.

Guidance of the user and the patient during Valsalva test

During the Valsalva test, the patient blows into a mouthpiece that is connected to the Finapres^® NOVA. The tablet provides instant feedback to the patient on this blown pressure and on the duration of the test. The operator can check the blown pressure to assess whether the subject has generated sufficient respiratory effort for an adequate Valsalva maneuver. When necessary, the pressure threshold and maneuver time can also be changed by the operator. When multiple Valsalva maneuvers are performed by the subject, the GAT application provides an overview of all available data. Thereby, the operator can select the best maneuver, which facilitates an accurate and quantified result.
