HRV is another device that evaluates the body’s autonomic regulatory functioning ability. This instrument, which has been used for years in major medical centers and hospitals, is a device that listens to the frequency sounds of the heart in order to monitor the subtle changes in the vibratory rates of the sympathetic and parasympathetic activities.
This simple 15-minute test accurately measures a person’s fitness and wellness levels. The readings are taken first in a supine position and then in a standing position, comparing the frequencies of the two.
In observing these subtle rhythmic patterns of the heart rate, this test is useful in comparing several different pre- and post- situations such as different treatment protocols and detoxification programs, allowing the practitioner to determine the effectiveness of any given treatment.
