Electrical energy Electrical energy Electrical energy is energy derived from electric potential energy or kinetic energy. When loosely used to describe energy absorbed or maybe delivered by an electrical circuit (for example, one provided by an electric power utility) "electrical energy" talks about energy which has been converted "from" electric potential energy. This energy is supplied by the combination of electric current and electric potential that is delivered by the circuit. At the point that this electric potential energy has been converted to another type of energy, it ceases to be electric potential energy. Thus, all electrical energy is potential energy before
Electrical cardiometry Electrical cardiometry Electrical cardiometry is a method based on the model of "Electrical Velocimetry", and non-invasively measures stroke volume (SV), cardiac output (CO), and other hemodynamic parameters through the use of 4 surface ECG electrodes. Electrical cardiometry is a method trademarked by Cardiotronic, Inc., and is U.S. FDA approved for use on adults, children, and neonates. The measured bioimpedance over time can be expressed as the superposition of three components: where Z is the quasi-static portion of the electrical impedance (base impedance), ΔZ are the changes of impedance due to the respiratory cycle, and ΔZ are the changes of impedance
