Abstract :
Our project tried to improve the repeatability and quality of vital parameter measurements performed at home. Our efforts focused on four issues, (a) a new electrode reversal detection algorithm that can correctly decide whether electrodes were reversed in 94.87% of the cases and can determine the proper reversal order in 85.32% of the cases, (b) the influence of electrode misplacements (1 cm) was studied by comparing QRS, PQ, QT, R, T and ST60 parameters. We found significant differences between the correctly positioned and misplaced parameters which underlines the importance of correct placement, (c) a modified Minnesota coding system was developed which was 9.3% more efficient when coding the 3-1, 3-2, 6-4-1, 7-1-1, 7-2-1, 7-3, 7-4 rules and (d) a lead estimation process is developed which estimates the unmeasured precordial leads form the measured I, II, V2 leads with 98.09% correlation in average.
