A wavelet-based VCG QRS loop boundaries and isoelectric coordinates detector

Frontiers in Physiology, 2022
This paper deals with a wavelet-based algorithm for automatic detection of isoelectric coordinates of individual QRS loops of VCG record. Fiducial time instants of QRS peak, QRS onset, QRS end, and isoelectric PQ interval are evaluated on three VCG leads

Selected transformation methods and their comparison for VCG leads deriving

Alexandria Engineering Journal, 2022
Vectorcardiography (VCG) as an alternative form of 12-lead ECG is another method of measuring the electrical activity of the heart. The use of vectorcardiography in clinical practice is not common, but VCG leads can be derived from 12-lead ECG.

Debatable issues in automated ECG reporting [PDF]

, 2017
Although automated ECG analysis has been available for many years, there are some aspects which require to be re-assessed with respect to their value while newer techniques which are worthy of review are beginning to find their way into routine use.

Sobolev tests of goodness of fit of distributions on compact Riemannian manifolds

, 2005
Classes of coordinate-invariant omnibus goodness-of-fit tests on compact Riemannian manifolds are proposed. The tests are based on Gin\'{e}'s Sobolev tests of uniformity. A condition for consistency is given.
