  • mõõtetehnoloogia, mis võimaldab mõõta inimese rindkere üldist elektrijuhtivust ja selle ajalisi muutusi, et pidevalt uurida mitmeid kardiodünaamilisi suurusi, nagu insuldi maht, südame löögisagedus, südame väljund, vatsakeste väljutamisaeg jne, mis kutsuvad esile impedantsi muutusi põhjustatuna kõrgsageduslikust, väikesest voolust, mis voolab läbi rindkere kahe täiendava elektroodipaari vahel
  • non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume, heart rate, cardiac output, ventricular ejection time, pre-ejection period and used to detect the impedance changes caused by a high-frequency, low magnitude current flowing through the thorax between additional two pairs of electrodes located outside of the measured segment
impedantskardiograafia preferred
Usage examples
  • Impedantskardiograafia seisneb nelja ühekordselt kasutatava kaksiktajuri paigutamist kaelale ja rinnale, et edastada ja tuvastada rindkere elektrilisi ja impedantsi muutusi, mida kasutatakse kardiodünaamiliste suuruste mõõtmiseks ja arvutamiseks.
impedance cardiography preferred
Usage examples
  • With impedance cardiography, the placement of four dual disposable sensors on the neck and chest are used to transmit and detect electrical and impedance changes in the thorax, which are used to measure and calculate cardiodynamic parameters.
