Abstract

A portable 31 lead Laplacian ECG (LECG) map was plotted in real time using a hierarchical programming system called LabVIEW based on dataflow programming. The monitor displayed all LECG waveforms and isopotential and isochronal maps showing the propagation sequence of the heart from the chest surface shown in real time. The real time body surface LECG mapping method is feasible due to the high input impedance to the active bipolar concentric ring sensors
