DECREASE IN THE FUNCTIONAL ABILITIES OF THE HEART AS A RESULT OF EXPOSURE OF AN ORGANISM TO AN ELECTROMAGNETIC FIELD OF INDUSTRIAL FREQUENCY
E.V. Prokhvatilo
Power line electromagnetic fields can impair heart function, raising concerns about cardiovascular effects from constant electrical grid exposure.
Plain English Summary
This study investigated how electromagnetic fields from power lines affect heart function in animals. The research focused on industrial frequency EMF (typically 50-60 Hz) and measured changes in cardiac activity using electrocardiogram monitoring. The findings suggest that exposure to power line frequencies can decrease the heart's functional abilities.
Why This Matters
This research adds to growing evidence that power line electromagnetic fields affect cardiovascular function, not just cancer risk. Industrial frequency EMF (50-60 Hz) is everywhere in our electrical infrastructure, from transmission lines to household wiring. The science demonstrates that these fields can alter heart rhythm and function, which has immediate implications for people living near power lines or working in high-EMF environments. What makes this particularly concerning is that power line frequencies are constant exposures. Unlike cell phones you can turn off, the electrical grid operates 24/7. The reality is that millions of people live within 300 meters of high-voltage transmission lines, where magnetic field levels can exceed what this research suggests affects cardiac function.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 15, 30, 45, and 60 days
Study Details
To derive an in-depth description of the character of cardiac activity changes resulting from exposure to low-intensity EMP of industrial frequency and to study the functional abilities of the heart during physical stress.

These changes in cardiac activity pertain only to animals exposed to an EMP with an intensity of 1000 V/m. In other EMP intensities (500 and 100 V/m), similar changes were absent. Thus, an electromagnetic field of industrial frequency is biologically active in relationship to the cardiovascular system. Its impact causes a weakening of the force of myocardial contraction. This weakening is especially pronounced during functional stress and perhaps is connected with electrical disturbances (depolarization and repolarization), dystrophic processes, and insufficiency of the blood supply to the cardiac muscle. Thus, the widespread introduction of electromagnetic fields of industrial frequency in the environment, with its resulting biological impact, necessitates the regulation of the above-mentioned factors for public health reasons. These data can be utilized as a basis for determining permissible levels of voltage intensity given off by electromagnetic fields of industrial frequency in populated areas.
