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…

Jan 1, 2025
This animal study examined 50 Hz electromagnetic exposure dominated by a measured magnetic component (~11.15 µT) on cardiac function in Vimba vimba embryos. Using two experimental series, the authors report significant increases in embryonic heart rate with EMF exposure during incubation and during observation. The…

This paper discusses how low-energy, specifically modulated electromagnetic fields delivered via an active closed-loop medical device may temporarily alter plasma membrane ionic flow and heart oscillation dynamics. It frames heart rate dynamics as a surrogate for systemic synchronization/entrainment and suggests…
Physiological changes and symptoms associated with short-term exposure to electromagnetic fields: a randomized crossover provocation study.

Jan 1, 2022
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…

Jan 1, 2021
This double-blind randomized sham-controlled repeated-measures study examined short-term 50 Hz ELF-EMF exposure (28 μT) to the chest and its effects on HR and HRV in 34 healthy young men. HR deceleration occurred in both EMF and sham conditions, but several HRV indices (SDNN, RMSSD, LF, HF) increased only in the EMF…

Jan 1, 2020
This double-blind animal study examined whether RF EMF exposure slightly exceeding occupational limits affects heart rate variability in rabbits. Across two exposure setups (device-generated RF and real base-station downlink signals), the authors report increased HRV indices (HF-HRV and rMSSD) alongside lower heart…

Jan 1, 2019
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…

Jan 1, 2017
This engineering study describes miniaturized, flexible, battery-free wearable pulse oximetry systems that use near-field communication (NFC) for wireless operation. The devices capture and transmit photoplethysmograms to derive blood oxygenation, heart rate, and heart rate variability. The abstract reports…

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…
The influence of low-frequency magnetic field on plasma antioxidant capacity and heart rate.
Research
RF Safe Research Library
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,…
