Comparison of a new reduced lead set ECG with the standard ECG for diagnosing cardiac arrhythmias and myocardial ischemia

Best leads in the standard electrocardiogram for the emergency detection of acute coronary syndrome

“…27 Ischemia detection with reduced lead sets have, in fact, so far, only been successful when the omitted leads have been calculated or when a derived 12-lead ECG has been used. [28][29][30] Thus, in reduced lead sets, it seems that ischemia detection will not be satisfactory if only the ST segment is monitored. To our knowledge, detection of ischemia using multiple ECG variables in reduced lead sets has not previously been tested.…”

Evaluation of limited and alternative lead sets for the reconstruction of the 12-Lead electrocardiogram and Body Surface Potential Maps

“…For the evaluation of the 12-lead ECG reconstruction from a limited set of leads, we focused on five available limited lead systems [2,3,4,5,6] as presented in Table 1. For the reconstruction coefficients that were not publicly disclosed, coefficients were calculated from a learning set of 2372 10-second ECG recordings [3].…”

“…Well-known standard configurations are the 12-lead ECG used for routine cardiac diagnosis and body surface potential maps (BPSMs) used to measure the full electrical activity on the body surface. These 12-lead and BSPM configurations contain redundant information and in the past various strategies based on limited or alternative lead sets have been proposed [1,2,3,4,5,6,7]. The purpose of this study is to evaluate the use of limited leads for reconstruction of the 12-lead ECG and BSPMs.…”

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

“…Most applications have converted the reduced lead sets to the standard 12-lead signals based on some regression algorithms, and then applied standard 12-lead algorithms to the converted data [1][2][3]. To do that, we would assume the morphology of relevant ECG segments in converted lead data do not have significant changes compared to the standard 12-lead system.…”
