Abstract
Four first electrodes are attached on right clavicle, the vicinity of on left clavicle, on right lowermost rib, and the position on left lowermost rib, corresponding to limb leads 12-lead electrocardiogram (ECG). Two second electrodes are attached on such positions of the living body that correspond to a lead Vand a lead Vof 12-lead ECG. First ECG data set correspond to leads I and II of 12-lead ECG. A second ECG data set including the leads Vand V. A heart vector is calculated on the first and second ECG data sets, and predetermined first lead vectors of leads I, II, Vand V. A third ECG data set including leads V, V, Vand Vis calculated based on the heart vector and predetermined second lead vectors of leads V, V, Vand V. A fourth ECG data set from leads III, aVR, aVL and aVF of 12-lead ECG based on the first ECG data set. The 12-lead ECG is derived based on the first to fourth ECG data sets.
