Assessment of signal quality and electrode placement in ECGs using a reconstruction matrix

摘要: We estimate that as much 5% of all recorded ECGs worldwide may, to some degree, suffer from poor signal quality or incorrect electrode positioning, which often interferes with correct interpretation the ECG. Proper training ECG technicians and regular inspection is necessary achieve a high standard. Due large amounts daily, we devised an automatic method based on conversion into VCG back again reconstructed Incorrectly placed electrodes well different types noise can be detected level accuracy. used this assess in learning set Physionet/Computing Cardiology Challenge 2011, giving 92.2% corresponded sensitivity 97.0 specificity 75.1%
