What is VAT?

Vestibular Autorotation Test (VAT) measures vestibular ocular reflex(VOR) function. VOR stabilizes visual images by maintaining eye-head coordination during head movement. Specifically, it steadies the visual image during motion when fixated on a target. This process is important for a person’s ablity to perceive speed and direction of mody movement. Imporper, or out of tolerance coordination can result in or contribute to dizzyness, disequillibrium, or vertigo.

VAT testing measures physiologically significant movement with a velocity great enough to represent real world activity, such as walking and running. This range can be up to 6Hz in two dimensions; yaw and pitch. This differs from more traditional testing, such as ENG testing in that it is faster movement, and measures motion in two directions, horizontal and vertical. ENG only measures horizontal motion.

What is Electronystagmogram(ENG)?

ENG measures nomral eye movement and involuntary rapid eye movements called nystagmus. It also checks the muscles that control eye movement. This test monitors how the eyes, inner ear, and brain help maintain your balance. Any damage or problems in these areas can cause chronic dizziness or vertigo.

During ENG testing, electrodes are connected near the eyes to monitor their movement. A baseline recording is done while the head is station while testing is done with head movement and following a moving object. Additional testing called a Caloric test may be performed, which involves running cool or warm water in the ears. Cool or warm air may be blown into them instead. This test is not performed if the patient has a perforated ear-drum, as water can get into the middle ear and cause infection in that case.

While VAT measures more dimensions, that does not mean ENG testing is not needed. If a VAT doesn’t produce positive results, ENG testing may, as it detects abnormalities in slower movement ranges, and can help guide therapy in these cases.

Holter monitoring is a test procedure that uses a holter monitor to record heart rate during regular activity over a 24-48 hour time period. The test uses electrodes placed on the chest connected to a small battery operated monitor that records the information. The monitor can be carried in a pocket or small pouch attached to the neck or waist.

Normal activity should be observed during this test, while exercise may be requested by the doctor if symptoms have previously occurred. Make sure to record all activity and symptoms experienced, including the time they occurred, so the doctor may match the monitor data.

Event Monitors

Event monitors are similar to Holter monitors in that they monitor heart activity. Unlike Holter monitors, however, event monitors only record during symptoms. When experiencing symptoms, the event monitor must be started manually to record heart activity. Because event monitors need to record less data than Holter monitors, they are smaller in size, some being wearable wrist watches.

Fields marked with an * are required

Vascular studies are non-invasive procedures performed to assess blood flow in arteries and veins. These tests use doppler ultrasound to determine vascular conditions throughout the body. No radiation is used, and the skin is not pierced.

You may be advised for vascular studies if you are experiencing early symptoms of decreased blood flow in arteries and veins in the arms, legs, and neck. They may also be performed to assess the effectiveness of previous procedures and vascular devices such as an A-V fistula.

Echocardiology is the interpretation of ultrasounds in order to perform imaging of the heart. Ultrasound techniques create 2-D slices of the heart and color doppler is used to image blood flow.

ACI performs transthoracic echocardiograms, or TTE. TTE is a non-invasive procedure (skin is not pierced) that images the heart through the chest wall. The procedure uses ultrasound detected by a transducer probe placed on different points on your chest and abdominal section in order to create the heart images. No radiation is used, and no preperation like fasting is needed. There are no known risks, however the doctor may need to press down hard on the probe in order to create the images.
