   Abstract:
   This paper considers how many and which locations on the body surface must be measured (by taking ECGs at these positions) to be able to determine consistently the total-body QRS surface-potential distribution as it varies in time. The approach involves applying principal component analysis followed by a minimum-r.m.s. estimation method. The conclusions are the following: the surface potential distribution is computed from measuring positions approximating the Frank VCG locations or the standard ECG locations, then for some cases accuracy is unacceptably poor; for consistently acceptable accuracy, a minimum of 24 properly placed measuring locations is required
