Jan 1, 2025
This animal experimental study exposed chicken embryos (CAM) continuously to 2.4 GHz Wi-Fi at an average power density of 300 μW/m2 for 9 or 14 embryonic days. H&E staining reportedly showed no significant structural differences in large vessel walls versus controls. However, special staining reported decreased…
Impact of Radiofrequency Electromagnetic Fields on Cardiac Activity at Rest: A Systematic Review of Healthy Human Studies
Research

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…
Electromagnetic fields - do they pose a cardiovascular risk?
Research
RF Safe Research Library
Jan 1, 2023
This study assessed short-term autonomic cardiac responses to RF EMF exposure using HRV metrics in 30 healthy young adults. During 2400 MHz (Wi-Fi) exposure applied to the chest for 5 minutes, HF-HRV decreased and the sympathetic-related 0V% index increased compared with 2600 MHz (4G) exposure, while RR intervals did…

Jan 1, 2022
This study assessed whether 915 MHz RF-EMF exposure alters oxidative stress and apoptosis markers in cardiac cells and mouse heart tissue. The authors report no statistically significant differences in apoptotic profile, antioxidant capacity, tissue integrity, or expression of apoptosis/antioxidant genes after…

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…
[The reaction of the circulatory system to stress and electromagnetic fields emitted by mobile phones - 24-h monitoring of ECG and blood pressure].
Research
RF Safe Research Library
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…
Low frequency electromagnetic field decreases ischemia-reperfusion injury of human cardiomyocytes and supports their metabolic function.

Jan 1, 2018
This in vitro study tested whether extremely low frequency/low frequency electromagnetic field (LF-EMF) exposure modifies ischemia-reperfusion injury in human cardiac-related cell types. Using LDH and MMP-2 activities and fluorescein diacetate staining, the authors report that short courses of LF-EMF reduced cellular…
Effect of zero magnetic field on cardiovascular system and microcirculation.

Jan 1, 2016
This study examined cardiovascular and microcirculation responses in healthy adults under zero magnetic field conditions generated by an "ARFA" magnetic field modeling facility. Participants were tested twice, once in zero magnetic field and once in a sham condition, with measures including capillary blood flow,…

Jan 1, 2015
This pre/post study measured circulating microRNA profiles in 30 atrial fibrillation patients before and 3 months after radiofrequency ablation, comparing results with 10 healthy controls. The authors report that numerous miRNAs differed from controls at baseline and shifted after ablation, with several highlighted…

Jan 1, 2015
This study enrolled 70 patients with primary hyperthyroidism and 74 healthy volunteers and assessed carotid artery structure and function using ultrasound RF data parameters before and after 131I therapy. Hyperthyroid patients showed worse carotid IMT and stiffness-related measures than controls at baseline. After…
Effects of 900 MHz electromagnetic field emitted by cellular phones on electrocardiograms of guinea pigs.

Jan 1, 2014
This animal study examined whether RF-EMF from cellular phones affects electrocardiograms in guinea pigs. Thirty guinea pigs were randomized to control (no exposure) or RF-EMF exposure (890–915 MHz; SAR 0.95 W/kg) for 12 hours per day over 30 days. The study reports no significant effects on ECG findings under these…
