  • Electrocardiograph

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

  • 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.  

  • Electricity

    A form of energy that is generated by the interactions of positive and negative charges and that exhibits magnetic, chemical, mechanical, and thermal effects. The movement of particles around an atom that creates pure energy.  

  • Electric field

    A electric field that may surround an object placed in a rapidly changing magnetic environment, such as one generated by a magnetic resonance imaging device. The region of electrical sensitivity surrounding a charged conductor or charged object.  

  • Electrical stimulation

    Use of electric current to affect a tissue, such as nerve, muscle, or bone. In the latter case, the stimulation is used to facilitate and hasten healing of fractures.  

  • Electrical source imaging

    A means of mapping the electrical activity of organs such as the brain or heart in order to diagnose or treat diseases such as seizures or dysrhythmias. ESI relies on the collection via external sensors of the electrical activity generated by multiple tissue sites within an organ, and the mathematical manipulation of that data to…

  • Electrical patch

    An electrical device for delivering medications transdermally. The slight electric current used in electrical patches allows larger molecules to be transported through the skin. This technique differs from electrophoresis by the electrical current used, which increases the permeability of the skin.  

  • Electrical leakage

    The presence of unwanted current from an electrical device, such as a patient monitoring or treatment device.
