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

A knowledge-based technique for automated detection of ischaemic episodes in long duration electrocardiograms.
TL;DR: A novel method for the detection of ischaemic episodes in long duration ECGs is proposed that includes noise handling, feature extraction, rule-based beat classification, sliding window classification and ischaemia episode identification, all integrated in a four-stage procedure.

TL;DR: It was observed that the linear classification algorithm was not able to detect heart attack in noisy data, whereas the support vector machine (SVM) algorithm with polynomial kernel with extended time–frequency features using extended modified B-distribution (EMBD) showed highest accuracy and was able to detection 97.4% and 96.3% of ST-elevation myocardial infarction and non-ST-Elevation MI, respectively.

A simple real-time QRS detection algorithm
TL;DR: A simple algorithm using topological mapping has been developed for a real-time detection of the QRS complexes of ECG signals and to describe a change of curvature, the authors derive modified spatial velocity (MSV), from MSV the authors can locate Q RS complexes more easily.

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.
