TLDR
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.Abstract:
We have developed a real-time algorithm for detection of the QRS complexes of ECG signals. It reliably recognizes QRS complexes based upon digital analyses of slope, amplitude, and width. A special digital bandpass filter reduces false detections caused by the various types of interference present in ECG signals. This filtering permits use of low thresholds, thereby increasing detection sensitivity. The algorithm automatically adjusts thresholds and parameters periodically to adapt to such ECG changes as QRS morphology and heart rate. For the standard 24 h MIT/BIH arrhythmia database, this algorithm correctly detects 99.3 percent of the QRS complexes.read more

One-pass training of optimal architecture auto-associative neural network for detecting ectopic beats
TL;DR: In this paper, a method for ectopic beat detection in the electrocardiogram using an auto-associative neural network is described, which uses principal component analysis to optimise the complexity of the neural network and uses singular value decomposition to determine the initial values for the weights.

Self-compassion Modulates Heart Rate Variability and Negative Affect to Experimentally Induced Stress
TL;DR: In this paper, the impact of self-reported self-compassion on physiological stress response and negative affect induced in a laboratory setting was investigated, showing that selfcompassionate individuals reported less negative affect in response to stress.

Threshold-Independent QRS Detection Using the Dynamic Plosion Index
TL;DR: An algorithm proposed earlier for epoch detection from ILPR is extended to the problem of QRS detection and its performance is found to be comparable to the state-of-the-art algorithms, despite its threshold independence and simple decision logic.

Online digital filters for biological signals: some fast designs for a small computer.
TL;DR: The possibilities for extending the class of lowpass recursive digital filters to include high pass, bandpass, and bandstop filters are described, and experience with a PDP 11 computer has shown that these filters may be programmed simply using machine code, and that online operation at sampling rates up to about 8 kHz is possible.
