Peripheral Blood Flow Measurements During Application of Pulsed High Frequency Currents
William James Erdman II · 1960
This 1960 study by William James Erdman II investigated how pulsed high-frequency radiofrequency currents affect blood circulation in human subjects, using plethysmograph measurements to track peripheral blood flow changes. The research examined the biological effects of short-wave diathermy treatments, which use RF energy to generate heat in body tissues. This early work documented measurable physiological responses to RF exposure, contributing to our understanding of how electromagnetic fields interact with human circulatory systems.
