Jan 1, 2025
This systematic review evaluated evidence on RF-EMF exposure and cardiac activity (heart rate and heart rate variability) in healthy humans at rest. Across 28 studies spanning 100 to 110,000 MHz and exposures from minutes to a week, most studies reported no significant effects on resting heart rate, and HRV findings…

This randomized blinded crossover provocation study compared short-term RF-EMF exposure mimicking mobile phone base stations versus sham in people with IEI-EMF and controls. Symptom reporting and physiological measures (blood pressure, heart rate, heart rate variability) were similar between provocation and sham…

In a worker sample undergoing 24-hour ECG and ambulatory blood pressure monitoring, higher self-reported daily mobile phone use (>60 minutes) was associated with higher systolic blood pressure in office measurement and at night. Higher occupational stress was associated with higher systolic and diastolic blood…

This engineering paper reports a prototype wearable patient-monitoring device that transmits vital-sign measurements via Bluetooth LE during MRI. Across 7 MRI acquisitions (25 minutes total), the authors report no Bluetooth packet loss, increased PPG noise during MRI, and no effect on temperature/humidity readings.…

Jan 1, 2011
This paper describes the design and preliminary implementation of a mobile-phone-based wireless blood pressure monitoring system that transmits data via Bluetooth and computes blood pressure and heart rate on the phone. The authors state that experiments demonstrated the device’s reliability and stability, and that…

Jan 1, 2009
This animal study exposed Sprague-Dawley rats to a 40 Hz, 7 mT time-variable magnetic field and measured ECG heart rate and plasma antioxidant capacity before and after exposure, including after 14 days. The authors report a significant decrease in heart rate after 14 days. Antioxidant defence findings were mixed,…
