Radiofrequency electromagnetic field affects heart rate variability in rabbits.
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 rate during exposure. They interpret these changes as increased cardiac vagal control under RF EMF exposure.
Key points
- The study used 21 New Zealand white rabbits in a double-blind design.
- RF EMF exposure was 160 V/m for 150 minutes at ~1788 MHz (device source) or 1805β1870 MHz (base-station downlink range).
- HRV was analyzed from 5-minute recordings using time-domain (heart rate, rMSSD) and frequency-domain (LF and HF power) metrics.
- The authors report increased HF-HRV and rMSSD during RF EMF exposure.
- Lower heart rate during exposure was reported and interpreted as increased vagal control.
- Anesthesia/premedication differed between the two groups, which could influence HRV outcomes.
