Adapting ECG morphology changes from reduced-lead set by specifically trained algorithms for acute ischemia detection

Abstract

The reduced lead set in this study consists of a subset of 12-lead

Estimation performance of a reduced lead system during continuous 12-lead ECG ST-segment monitoring

“…These systems estimate the 12-lead ECG from as few as 5-6 electrodes. 2,3 RLSs have been shown to be capable of producing estimated 12-lead ECGs that closely resemble actual recorded 12-lead ECGs. 4 Nevertheless, differences between diagnoses obtained from estimated and actual recorded 12-lead ECGs have also been reported in some patients.…”

Using a Cell-to-ECG model to evaluate ischemia detection from different lead sets

“…However, the experiments carried in actual sampled ECGs showed the specifically trained criteria can adapt to the morphology change and improve the sensitivity significantly for acute anterior MI cases [13].…”

Improved 12-lead ECG reconstruction from lead sub sets by dynamic selection of frontal leads

“…For example, Drew et al [4] proposed a lead subset with leads I, II, V 1 and V 5 . With the coefficients published by Xue et al [7], the unrecorded lead V 2 can be reconstructed with dV 2 = 0.887330 * I + -0.091160 * II + 1.578620 * V 1 + 0.230214 * V 5 . The other unrecorded leads V 3 , V 4 and V 6 are reconstructed in a similar fashion, but with different coefficients.…”

“…In recent years, patient monitoring with lead subsets of the 12-lead electrocardiogram (ECG) and subsequent reconstruction of the unrecorded leads has been studied by various research groups [1,2,3,4,5,6,7]. Typical reduced lead set implementations in clinical practice use the independent frontal leads I and II and two of the six precordial leads to reconstruct the four unrecorded ECG leads using general and patient-specific coefficients.…”
