A process for sensing and analyzing electrical activity of the human heart includes the use of a set of electrodes for a first lead system and an ECG monitor design for use with a second lead system that is different from the first lead system. Output signals from the first lead system electrodes are connected to first, second and third channel inputs for the ECG monitor. The input signals to the ECG monitor are linearly transformed to output first, second and third ECG channels which are consistent with standard output for the first lead system. In linearly transforming the inputted signals to the ECG monitor, differences between the first lead system electrodes and the ECG monitor are manipulated either before the output signals from the first lead system electrodes are fed to the channel inputs for the ECG monitor, or after the ECG monitor has formed channels. Specifically disclosed herein is the transformation of signals between 1) a standard bedside system I lead system, 2) a standard EASI lead system, 3) a standard bedside system II lead system, and 4) a Dower EASI lead system.
