This study aimed to highlight on the influence of exposure to electromagnetic fields (EMFs) on the cardiovascular system in humans and experimental animals, from the recent articles regarding the cardiovascular effects of exposure to EMFs. EMFs might produce a variety of adverse in vivo effects such as heart problems, chest pain, and cardiovascular system disorders. Previous studies showed that an association between elevated magnetic field exposure and mortality of employer in electric utility industry jobs from arrhythmia-related causes and acute myocardial infarction influence heart rate variability by changing autonomic balance. EMF exposure can affect structure and function of cardiovascular system and may facilitate myocardial infarction by nuclear changing of cardiomyocytes. Exposure to EMFs induced pain or pressure in the chest area, heart palpitations, and/or an irregular heart beat. The symptoms resemble a heart attack and thus contribute to even more anxiety. Also, exposure to EMFs caused highly significant increases in the activeties of serum creatinine phosphokinase, lactate dehydrogenase and aspartate amino-transferase enzymes, and decreases in plasma calcium level and total anti-oxidant capacity. Rats exposed to EMF showed increases in blood pressure, the absolute and relative whole heart and left ventricular weights. On the other hand, the heart rate was significantly reduced in rats exposed to EMF.
