1. a vectorcardigram instrument implementation method is characterized in that:

  • may further comprise the steps;

    Step 1. is gathered the lead orthogonal ECG data of system of Frank, each space voltage amplitude constantly of recorder'"'"'s systemic heart bio electricity;

    Step 2. is set virtual axis of leads;

    the axis of leads of vectorcardigram was made up of one group of virtual leading with software set, and all there are a face attribute and an angle attribute each virtual leading, and determines the direction of axis of leads.In separately 0~

    360 degree scope, set 0~

    18 axis of leads on face amount (F), plane of structure (H) and side (S), three faces are provided with 54 virtual axis of leads altogether, can arbitrarily adjust its axis of leads angle, and the minimum angle between the axis of leads is 0.5 degree;

    Step 3. is represented each transient voltage component in the space with one " spatial point ".The far-end of each spatial point is linked to be a curve, has just formed three-dimensional heart vector loop.After three-dimensional heart vector loop is projected in volume, horizontal stroke, three planes of side, form the plane vectorcardiogram (Vectorcardiogram, VCG);

    On three plane ring bodies, do the projection of some the virtual axis that lead again, by COMPUTER CALCULATION and draw the vectorcardigram waveform of this axis of leads from different angles.
