Abstract

Abstract Summary

Overview

This systematic review and meta-analysis investigates the effects of man-made electromagnetic fields (EMFs) on heart rate variability (HRV), a parameter indicative of the cardiac autonomic nervous system activity. While studies have shown conflicting results, this analysis aims to find a common ground in understanding how EMFs might alter cardiovascular health through HRV.

Findings

• A significant decrease was reported in SDNN, SDANN, and PNN50 indices, which can affect cardiovascular risk.
• No significant changes were noted in LF and HF ratios, and no difference was observed in LF/HF.

Published literature was sourced from four key databases including Web of Science, PubMed, Scopus, and Embase, leading to the inclusion of 15 original studies in this meta-analysis.

Conclusion

The connection between EMFs and changes in HRV measures suggests a potentially harmful impact on cardiovascular health. Such findings underscore the need for caution in the use of devices emitting EMFs, like cell phones, particularly among young people who are more frequently exposed.
