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

Support Vector Machines for Automated Recognition of Obstructive Sleep Apnea Syndrome From ECG Recordings
TL;DR: The results suggest superior performance of SVMs in OSAS recognition supported by wavelet-based features of ECG and demonstrate considerable potential in applying SVM in an ECG-based screening device that can aid a sleep specialist in the initial assessment of patients with suspected OSAS.

Support vector machine-based arrhythmia classification using reduced features of heart rate variability signal
TL;DR: The proposed algorithm is completely based on the HRV (R-R interval) signal which can be extracted from even a very noisy ECG signal with a relatively high accuracy and leads to an effective reduction of the processing time, which provides an online arrhythmia classification system.

A novel method for detecting R-peaks in electrocardiogram (ECG) signal
TL;DR: This paper demonstrates that the proposed preprocessor with a Shannon energy envelope (SEE) estimator is better able to detect R-peaks than other well-known methods in case of noisy or pathological signals.

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.
