The use of electrical devices has gradually increased throughout the last century, and scientists have suggested that electromagnetic fields (EMF) generated by such devices may have harmful effects on living creatures. This work represents a systematic review of collective scholarly literature examining the effects of EMFs on the heart. Although most works describing effects of EMF exposure have been carried out using city electric frequencies (50–60 Hz), a consensus has not been reached about whether long- or short-term exposure to 50–60 Hz EMF negatively affects the heart. Studies have indicated that EMFs produced at cell-phone frequencies cause no-effect on the heart. Differences between results of studies may be due to a compensatory response developed by the body over time. At greater EMF strengths or shorter exposures, the ability of the body to develop compensation mechanisms is reduced and the potential for heart-related effects increases. It is noteworthy that diseases of heart tissues such as myocardial ischemia can also be successfully treated using EMF. Despite the substantial volume of data that has been collected on heart-related effects of EMFs, additional studies are needed at the cellular and molecular level to fully clarify the subject. Until the effects of EMF on heart tissue are more fully explored, electronic devices generating EMFs should be approached with caution.

The heart is a contractile organ that can generate its own rhythm. The contraction, or the rhythm, of the heart may be influenced by electromagnetic field (EMF) exposure, because of the heart's excitability characteristic. In previous studies, different methods have been used to study the possible effects of an extremely low frequency electromagnetic field (ELF-EMF) on the heart. But the studies’ designs were not similar, and the results were also different. Recent studies have shown some evidence that short-term EMF exposure can influence the heart more than long-term exposure. This study investigated how the heart is affected in the first EMF exposure. In a simulation of the daily exposure of humans to a power frequency, Wistar albino rats were used. By utilizing the Helmholtz-coil set, we obtained a 50-Hz, 1-μT EMF and examined rat heart activity during short-term EMF exposure. No effect was observed under this exposure condition. The results obtained do not confirm a possible mechanism in the electrical activity of the rat heart model.

Anadolu adaçayı (Salvia fruticosa), Lamiaceae familyasına ait bir bitki olup, Anadolu’da geleneksel halk hekimliğinde yaygın olarak kullanılmaktadır. Bitkinin yaprakları çay şeklinde tüketilir ve yapraklarından uçucu yağ elde edilir. Salvia fruticosa bitkisi farmasötik ajan olarak (antioksidan, antikanser, antimikrobiyal, antifungal, antihiperglisemik, antihipertansif vb.) kullanımı dışında aromaterapi, parfümeri ve kozmetik sektöründe; yiyeceklerde baharat, aroma verici ve koruyucu olarak pek çok alanda kullanıma sahiptir. Ancak bitkinin irrasyonel kullanımı ciddi yan etkilere ve komplikasyonlara yol açmaktadır. Bu derleme, Salvia fruticosa’nın botanik özelliklerini, uçucu yağ bileşenlerini, bu bileşenlerin potansiyel terapötik etkilerini ve neden olabileceği olası toksik etkileri değerlendirmeyi amaçlamaktadır.
