Heart Rate Variability (HRV) and Autonomic Balance: IGEF Study

Participants and methods

IGEF assessed 10 participants aged 19–67 who identified as sensitive to electromagnetic environments. They used Somavedic Medic at work or at home. The Stress Pilot Plus system measured heart rate variability (HRV), including respiratory sinus arrhythmia, as an indicator of autonomic regulation.

Each participant’s follow-up readings were compared with their own baseline. Follow-up times varied from 2 to 28 days.

Results

• IGEF classified 8 out of 10 participants as showing improved HRV. One participant’s endpoint decreased, and one did not show the reported improvement.
• The report presents individual values and age-referenced classifications. It does not report an aggregate statistical test or a prespecified threshold for improvement.

Study context

Participants were self-selected, and the assessment used their own starting readings rather than a sham or separate control group. Randomization and blinding are not described. HRV was measured; circulation, energy and recovery outcomes were not directly measured.
