  • 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.  

  • Electrocardiograph

    A device for recording changes in the electrical energy produced by the action of heart muscles. The apparatus employed for generating an electrocardiogram.  

  • Signal-averaged electrocardiogram

    An electrocardiographic study, usually performed on patients with unexplained loss of consciousness or suspected dysrhythmias, in which hundreds of QRS complexes are collected, filtered, and analyzed to discover the presence or absence of certain abnormalities in the conducting system of the ventricle. These abnormalities, called late potentials, point to an increased risk of ventricular tachycardia…

  • Exercise electrocardiogram

    A record of the electrical activity of the heart taken during graded increases in the rate of exercise.  

  • Electrobiology

    The science of electrical phenomena in the living body.  

  • Electroacupuncture

    Stimulation of acupuncture points using transcutaneous electrical nerve stimulators (TENS) or other therapeutic electrical stimulation currents applied via needle or surface electrodes.  

  • Static electricity

    Electricity generated by friction of certain materials.  

  • Positive electricity

    An electric charge caused by loss of negatively charged electrons.
