ECG changes in humans exposed to 50 Hz magnetic fields.
Possible health issues of ELF EMFs include cardiovascular effects since both electrocardiogram and heart-rate changes have been reported in the literature. A non-linear relationship between field strength and biological response has been reported in some studies. In this study, a total of 59 subjects, divided into three independent magnetic field strength groups, were compared. A calculated 12-...
متن کاملThe Study of ECG Changes in Humans Exposed to 50 Hz Electromagnetic Fields
Introduction: It has been reported that cardiovascular effects are among the possible health effects of being exposed to extremely low frequency electromagnetic fields (ELF EMSs). Material and Methods: This study has been conducted to evaluate the long term effects of exposure to magnetic and electric fields on electrocardiogram signal changes. Nine power transmission posts having different vol...

متن کاملNeurovegetative disturbances in workers exposed to 50 Hz electromagnetic fields.
OBJECTIVES Since the circulatory and nervous systems are composed of electrically excitable tissues, it is plausible that they can be stimulated by electromagnetic fields (EMF). No clinical studies have as yet been carried out to explain whether and how occupational exposure to 50 Hz EMF can influence the neurovegetative regulation of the cardiovascular function. The present project was underta...
متن کاملAre 50/60 Hz magnetic fields carcinogenic
Magnetic fields are present everywhere in our environment. They are commonly measured in Tesla (T), the international unit for magnetic flux density. One Tesla is a very high magnetic field. Human exposures to such high fields occur only with magnetic resonance imaging machines (MRI machines which are used for medical imaging), which produce magnetic field levels up to a few Tesla. To describe ...
