Assuming two positive overlapping signals, with known shapes, the proposed method estimates the distances between their mean positions, width and area ratios. The data are two profiles representing the component shapes: no parametric model is assumed. The algorithm seeks shape equality between a linear combination of observation and first...

Stress tests are typical protocols that exhibit T waves changes for healthy and ischemic subjects. ST-T elevation is one example among others that characterizes ischemic patient. A more complex description of T wave changes needs extended models with a cost of higher identification pitfalls. We propose here to work in the inverse normalized...

The aim of this study was to investigate the variability of P wave morphology recorded in a close distance to precordial ECG leads. The study consisted of 60 cardiac patients. The ECG signals interpolated at points located at a distance up to 7 cm from the precordial lead location were compared to signals recorded from precordial leads. The...

New statistical and spectral detectors, the modified matched pairs t-test, the extended spectral method and the modified spectral method, was proposed for T-wave alternans (TWA) detection gaining robustness according to trend and single frequency interferences. They were compared to classic detectors such as matched pairs t-test, unpaired...
