Abstract: Multiple wireless sensor assemblies are individually attached to standard body locations for EKG signal recording. The sensors measure small biopotential signals at short distances on the body sites, and the small signals are used to calculate an output signal that resembles a conventional EKG measurement signal over the long distance between the sensors. An algorithm is employed to calculate the standard EKG signal using the two measurement sites' data and an attenuation value between sensor contacts which has been previously measured.
