Demonstration of a novel wireless three-pad ECG system for generating conventional 12-lead signals

Wireless monitoring of a patient's electrocardiogram (ECG) is a typical application in mobile healthcare area. Inspired by application of linear transformations to ECG signals obtained in a vectorcardiographic system, we propose the wireless three-pad ECG system (W3ECG). Signals obtained from these three pads, plus their placement information, make it possible to synthesize conventional 12-lead ECG signals. W3ECG's system-level design, pad placements and evaluations are presented in a separate paper. This paper details W3ECG's pad design, software implementation, and experimental studies.
