8. it is according to claim 7 detection human body multiple lead electrocardiogram detection method, it is characterised in that：Described
I lead electrocardiosignal Lead I and the IIth lead electrocardiosignal Lead II are transmitted separately to process in controller obtain
III lead electrocardiosignal Lead III, AVL lead electrocardiosignal Lead AVL, AVR lead electrocardiosignal Lead AVR and AVF leads
Joining electrocardiosignal Lead AVF refers to：
Lead III=Lead II-Lead I；
Lead AVR=-Lead II+0.5 × Lead III；
Lead AVL=Lead I-0.5 × Lead II；
Lead AVF=Lead III+0.5 × Lead.
9. it is according to claim 7 detection human body multiple lead electrocardiogram detection method, it is characterised in that：Will be positioned at pin
Dry electrode on the inside of ring is arranged between two dry electrodes on the outside of pin ring, realizes being pinned outside pin ring simultaneously in two hands
During two dry electrodes of side, dry electrode on the inside of pin ring or so stress equalization is with foot's skin of fully fitting.
