Design and evaluation of a novel wireless reconstructed 3-lead ECG monitoring system

This paper presents a novel lead system based on a wearable wireless ECG sensor for long term homecare. The ECG monitoring system amplifies, filters, samples and transmits 3-lead signals to the Coordinator. The signals are displayed and analyzed on PC. In order to make the sensor more wearable and comfortable for patients, a new lead system is studied and discussed to find the new convenience placements for electrodes. Mason-Likar limb electrode placement is considered as standard lead system. A lot of experiments are implemented to explore the relationship between standard and new lead system. The best placements of new lead system are proposed by comparing the correlation coefficients between standard and new lead system. Multielement non-linear regression method is employed to reconstruct 3-lead signals from the new lead system. This paper provides a powerful evidence that the traditional electrode placements can be replaced by new placements which make the ECG system more convenience and compact.
