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

Reducing drivers' mental workload by means of an adaptive man-machine interface
TL;DR: It is argued that there is a more intelligent solution to the information overload issue, namely an adaptive man–machine interface that filters information presentation according to situational requirements, which is implemented as a projective real-time computational workload estimator which is based on the assessment of traffic situations detected from an on-board geographical database.

TL;DR: It is found that arousing disgust cues modulated the encoding of sensory noise and the degree to which trial-by-trial pupil fluctuations encoded this nonlinear interaction correlated with trial level confidence, suggesting that unexpected arousal regulates perceptual precision.

Sleep Apnea Screening by Autoregressive Models From a Single ECG Lead
TL;DR: This paper presents a method for obstructive sleep apnea screening based on the electrocardiogram (ECG) recording during sleep, and shows that the two classifiers are able to separate entirely (100%) the normal recordings from the apneic recordings.

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.
