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

Comparison of HRV parameters derived from photoplethysmography and electrocardiography signals
TL;DR: HRV analysis was applied on beat-to-beat intervals obtained from ECG and PPG in 19 healthy male subjects and the results showed that the smallest error happens in SDNN and SD2 with relative error of 2.46% and 2%.

Sudden cardiac death (SCD) prediction based on nonlinear heart rate variability features and SCD index
Hamido Fujita,U. Rajendra Acharya,Vidya K. Sudarshan,Dhanjoo N. Ghista,S. Vinitha Sree,Lim Wei Jie Eugene,Joel En Wei Koh +6 more
TL;DR: The proposed technique is able to identify the person at risk of developing SCD four minutes earlier, thereby providing sufficient time for the clinicians to respond with treatment in Intensive Care Units (ICU), and can serve as a valuable tool for increasing the survival rate of many cardiac patients.

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.
