Holtersystem 2F allows analyzing of signal-average ECG of high resolution in any selected moment on specified time limit or specified number of analyzing QRS-complexes, also on reaching specified noise level. Analysis is performed in Simson method and allows estimating so-called late ventricular potentials and length of signal-average Ð-wave. Following indices are calculated on measurement results:
length of filtered QRS complex
length of low-amplitude high resolution potentials in the final part of QRS complex
root-mean-square value of tension in the final part of QRS complex, calculated with "Vector magnitude"
