A wavelet-based ECG delineator: evaluation on standard databases
TL;DR: A robust single-lead electrocardiogram (ECG) delineation system based on the wavelet transform (WT), outperforming the results of other well known algorithms, especially in determining the end of T wave.

The principles of software QRS detection
TL;DR: The authors provide an overview of these recent developments as well as of formerly proposed algorithms for QRS detection, which reflects the electrical activity within the heart during the ventricular contraction.

The many metrics of cardiac chronotropy: a pragmatic primer and a brief comparison of metrics.
TL;DR: This paper focuses on pragmatic issues in obtaining measures of cardiac vagal control, and overviews a set of freely available software tools for obtaining several widely used metrics that putatively reflect sympathetic and/or parasympathetic contributions to cardiac chronotropy.

QRS detection using K-Nearest Neighbor algorithm (KNN) and evaluation on standard ECG databases
TL;DR: The proposed K-Nearest Neighbor (KNN) algorithm as a classifier for detection of QRS-complex in ECG is evaluated on two manually annotated standard databases such as CSE and MIT-BIH Arrhythmia database and clearly establishes KNN algorithm for reliable and accurateQRS-detection.
Journal ArticleDOI
Genetic design of optimum linear and nonlinear QRS detectors
TL;DR: The authors report on detectors including a linear or nonlinear polynomial filter, which enhances and rectifies the QRS complex, and a simple, adaptive maxima detector.

A Real-Time QRS Detection Algorithm
Jiapu Pan,Willis J. Tompkins +1 more
TL;DR: A real-time algorithm that reliably recognizes QRS complexes based upon digital analyses of slope, amplitude, and width of ECG signals and automatically adjusts thresholds and parameters periodically to adapt to such ECG changes as QRS morphology and heart rate.

Software QRS detection in ambulatory monitoring--a review.
Olle Pahlm,Leif Sörnmo +1 more
TL;DR: This review asserts that most one-channel QRS detectors described in the literature can be considered as having the same basic structure and a discussion of some of the current detection schemes is presented.

Limited Lead Selection for Estimation of Body Surface Potential Maps in Electrocardiography
TL;DR: An algorithm for optimal selection of a limited number of leads was developed and it was found that optimal sites are not unique, i.e., different sets of optimal sites may be found which perform equally well.

A Digital Filter for the ORS Complex Detection
TL;DR: In this article, a five-step digital filter was developed which removes components other than those of QRS complex from the recorded electrocardiogram (ECG), and the final step of the filter produces a square wave whose on-intervals correspond to the segments with QRS complexes in the original wave.
