  • Electrodialysis

    A method of separating electrolytes from colloids by passing a current through a solution containing both. A semipermeable membrane is usually used to aid in the separation, with one electrode on each side.  

  • Electrodiagnostic technologist

    A specialist in the use of neurological diagnostic devices, including electroencephalography, electromyography, polysomnography, and evoked potentials.  

  • Electrodiagnosis

    The use of electrical and electronic devices for diagnostic purposes. This technique is helpful in almost all branches of medicine, but particularly in investigating the function of the heart, nerves, and muscles.  

  • Electrodermal testing

    A technique used in complementary and alternative medicine to measure electromagnetic energy in the skin and to apply that information to diagnostic and/or therapeutic purposes.  

  • Electrocution

    Destruction of life by electric current. In the U.S. about 1000 people die of electrical shocks each year; about a fourth of these die of lightning strikes. A fatal injury caused by electricity entering the body and destroying vital tissues.  

  • Electrocorticography

    Recording of the electrical impulses from the brain by electrodes placed directly on the cerebral cortex.  

  • Electrocontractility

    Contraction of muscular tissue by electrical stimulation.  

  • Electrochemistry

    The science of chemical changes produced by or resulting in electricity.  

  • Electrocerebral silence

    In electroencephalography (EEG), the absence of detectable electrical activity in the cortex of the brain. The EEG tracing shows no deflections from its baseline. This finding is diagnostic of brain death.  

  • Electrocardiographical technician

    A technician who operates and maintains electrocardiographic machines, records the heart’s electrical activity, and provides data for diagnosis and treatment of heart ailments.
