  • Title: ["Ambulatory" monitoring of left ventricular function using a scintillation detection system. Evaluation of a new method].

    Journal: Schweiz Med Wochenschr; 1988 Nov 19; 118(46):1719-23. PubMed ID: 3212424.
    Abstract:
    To validate a new portable scintillation probe (VEST) for determination of LV function, 68 patients were studied after standard radionuclide angiography (RNA). Reproducibility of VEST LV-ejection fraction was good (rest r = 0.93; exercise r = 0.96) with unchanged probe position, somewhat less good after probe repositioning (r = 0.84) and correlated with RNA (rest r = 0.79; exercise r = 0.83). Long term measurements in 7 patients showed valid data for up to 12 hours. Combined with simultaneous two lead ECG recording VEST seems suitable for detection of transient changes of LV function such as occur during ischemia or due to drug treatment.
