A Pulse Wave is when the heart pumps and pushes out blood. When the heart pumps it generates a pulse wave which is a contour wave that travels along the arterial tree. The wave form is generated from the left ventricular chamber of the heart to the big aorta, and is reflected back when the big aorta bifurcates or divides into two arteries.

The actual test itself takes 3 minutes. However, on average, a screening from start to finish will take 20-30 minutes. The more questions and discussion, the longer the screening takes.

No, it is a completely non-invasive and painless test.

Sometimes a person’s hands may be too cold and the finger sensor is having a difficult time reading the pulse wave. Have them run their hands through some warm water or use a heating device to warm their finger for an accurate reading.

The Artifact Beat detects how accurate the data collection is during the 3-minute screening. This is why it is important to make sure that the individual stays still, doesn’t talk, and breathes normally during the three minute scan. It’s also important that the table or desk that the device is on isn’t being bumped or moved during the actual screening.
An accurate reading will give an Artifact Beat of 5 or less. If the Artifact Beat is 6 or more, one of a couple things needs to be evaluated. Did the person move, breathe irregularly, sit uncomfortably, and/or was distracted by outside noises or persons, etc during the screening? If so, have them retested. Other times, it may register on the first sentence, of the second paragraph, on Report 1, that “An abnormal heart beat was detected during the process of this examination”. If an abnormal heart beat was detected, then the Artifact Beats of more than 5 are acceptable.

Make sure all cords are pressed in all the way and power is on to the device. Make sure that you are using the same port, every time, for each screening (If the device is plugged it into a different port than what’s established on your computer and in the Device settings, it will not work and you’ll need use the correct port). If that doesn’t work, you may need to uninstall, and then reinstall the software onto your computer. The Training section of this website has specific instructions for troubleshooting.

The testing environment should be a comfortable, quiet place with bright light and proper temperature. Preparation testing day should be: During the measurement, do not move or talk, and stay rested, breathing normally. Avoid the test just after exercise and relax 10 minutes in measuring room before taking the test. Ensure the finger monitor is at heart level. Those who have arrhythmia are not recommended for the test. Avoid smoking, drinking caffeinated drinks or drugs 3 hours before taking the test. Avoid alcohol 24 hours before test. Remove nail polish. Place finger sensor on the left index finger. The ideal screening position is having the patient lie down with their hands flat at their sides; however this may not always be ideal with the environment. Therefore, it is acceptable to have a patient sit with feet flat on the floor, legs uncrossed, placing the heart sensor at heart level. Ensure that the patient does not press the sensor too hard against their chest. Also make sure that he patient’s finger is cool to warm (If the finger is cold, use running water or hand warmer to increase the finger temperature and blood flow).

First, using Frequency Domain Analysis, the three different frequencies of the Autonomic Nervous System are gathered (VLF (Very low frequency) – 0.0033-0.04Hz, LF (low frequency) – 0.04-0.15Hz (Also known as “Mayer” waves), and HF (High frequency) – 0.15-0.4Hz (Vagus Nerve)). Next, the frequencies are then used to see if they are in the normal ranges by using the following formulas: LF norm = LF / LF + HF – > Sympathetic nerve and HF norm = HF / Lf + HF – > Parasympathetic nerve. Finally, depending on the information gathered, a LF:HF ration is determined and then plotted to show how the Sympathetic and Parasympathetic nervous systems are working in conjunction with their norm and each other (normal (balanced) or hyper or hypo to their norms).

The Autonomic Nervous System (ANS) is constantly trying to keep the body in balance. As a result, it is very fluid and dynamic.
