Michael Borkin, N.D. of Santa Monica, Californian uses HRV (Heart Rate Variable) to assess the condition of his patients. In this informal study, heart rate was found to increase when subjects used a cell phone. Heart rate was stabilized when the subject put on a BioElectric Shield.

Dr. Borkin: “HRV is the measurement, in milliseconds, of the beat-to-beat changes in a subject’s heart rate, and it gives a glimpse of the state of the autonomic nervous system. This system controls the beating of the heart, the movement of the gastrointestinal tract, and the secretion of hormones. The HRV test is a good measurement of a body’s overall response to stimuli. We had the subject answer her cell phone, this time while wearing the BioElectric Shield. Her HRV monitor showed that her autonomic nervous system remained stable, with no change in her heart rhythms.”
