“…It should be noted that these three leads of the LC system may not correlate to FV leads [28], however, they can still be assumed to be less accurate form of heart vector components in directions different from those of Frank leads. As mentioned before, in our previous work [15] we have found FV system to produce consistent and robust reconstruction results compared to other 3-lead systems, it has motivated us to propose an orthogonal 3-lead system or the Lead Component system.…”

“…These basis leads in the aforementioned methodology is a subset of S12 system, hereafter will be referred as S12S system and hence, are readily available without any extra hardware or requirement. However, Maheshwari et al [15] have shown that such systems suffer from proximity effect and do not produce robust results compared to that obtained from Frank's leads. EASI system is a 3-lead system having electrode positions inspired from FV system, thus having standard positions, however, they have been found to contain insufficient information [8] and reconstruction of S12 from S12S has been shown to outperform reconstruction S12 from EASI.…”

“…None of the aforementioned methodologies aimed at finding application in remote health monitoring. In our previous works [11,15,21,22], we have focused on this applications of lead reconstruction in a RHM scenario. All possible combinations of subsets of 3-leads of S12 system (S12S systems) have been used to reconstruct the missing leads using personalized methodology and have been shown to produce superior results compared to other investigations by various researchers.…”

“…4 For the reconstruction of S12 from proposed LC system, V can be replaced by the S12 leads and l 1 , l 2 and l 3 can be replaced by PC 1 , PC 2 and PC 3 in (4) to obtain the corresponding transformation coefficients. In many previous works [12][13][14][15], S12S system consisting of leads I, II and V 2 have been used for reconstruction of missing precordial leads of S12 system and it is also the most often used ba-sis lead set, hence, we compare the reconstruction results of our proposed LC system with aforementioned S12S system. To do so, V will be replaced by missing precordial leads and l 1 , l 2 and l 3 will be replaced by I, II and V 2 in (4).…”

Remote Health Monitoring (RHM) applications encounter limitations from technological front viz. bandwidth, storage and transmission time and the medical science front i.e. usage of 2-3 lead systems instead of the standard 12-lead (S12) system. Technological limitations constraint the number of leads to 2-3 while cardiologists accustomed with 12-Lead ECG may find these 2-3 lead systems insufficient for diagnosis. Thus, the aforementioned limitations pose self-contradicting challenges for RHM. A personalized reduced 2/3 lead system is required which can offer equivalent information as contained in S12 system, so as to accurately reconstruct S12 system from reduced lead system for diagnosis. In this paper, we propose a personalized reduced 3-lead (R3L) system formation methodology which employs principal component analysis, thereby, reducing redundancy and increasing SNR ratio, hence, making it suitable for wireless transmission. Accurate S12 system is made available using personalized lead reconstruction methodology, thus addressing medical constraints. Mean R 2 statistics values obtained for reconstruction of S12 system from the proposed R3L system using PhysioNet's PTB and TWA databases were 95.63% and 96.37% respectively. To substantiate the superior diagnostic quality of reconstructed leads, root mean square error (RMSE) metrics obtained upon comparing the ECG features extracted from the original and reconstructed leads, using our recently proposed Time Domain Morphology and Gradient (TDMG) algorithm, have been analyzed and discussed. The proposed system does not require any extra electrode or modification in placement positions and hence, can readily find application in computerized ECG machines.

Smartphones that can support and assist the screening of various cardiovascular diseases are gaining popularity in recent years. The timely detection, diagnosis, and treatment of atrial fibrillation (AF) are critical, especially for those who are at risk of stroke. AF detection via screening with wearable devices should always be confirmed by a standard 12-lead electrocardiogram (ECG). However, the inability to perform on-site AF confirmatory testing results in increased patient anxiety, followed by unnecessary diagnostic procedures and treatments. Also, the delay in confirmation procedure may conclude the condition as non-AF while it was indeed present at the time of screening. To overcome these challenges, we propose an efficient on-site confirmatory testing for AF with 12-lead ECG derived from the reduced lead set (RLS) in a wireless body area network (WBAN) environment. The reduction in the number of leads enhances the comfort level of patients as well as minimizes the hurdles associated with continuous telemonitoring applications such as data transmission, storage, and bandwidth of the overall system. The proposed method is characterized by segment-wise regression and a lead selection algorithm, facilitating improved P-wave reconstruction. Further, an efficient AF detection algorithm is proposed by incorporating a novel three-level P-wave evidence score with an RR irregularity evidence score. The proposed on-site AF confirmation test reduces false positives and false negatives by 88% and 53% respectively, compared to single lead screening. In addition, the proposed lead derivation method improves accuracy, F 1 -score, and Matthews correlation coefficient (MCC) for the on-site AF detection compared to existing related methods.
