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

Nonlinear Methods Most Applied to Heart-Rate Time Series: A Review
Teresa Henriques,Maria Ribeiro,Andreia Teixeira,Luísa Castro,Luís Antunes,Cristina Costa-Santos +5 more
TL;DR: This paper reviews the nonlinear methods most used to assess heart-rate dynamics based on concepts of chaos, fractality, and complexity: Poincaré plot, recurrence plot analysis, fractal dimension, detrended fluctuation analysis, Hurst exponent, Lyapunov exponent entropies, and symbolic dynamics.

Discrimination power of long-term heart rate variability measures
TL;DR: The results revealed that the standard deviation of all normal-to-normal beat intervals (SDNN) has the highest class discrimination power and a Bayesian classifier based on this index achieves sensitivity and specificity rates of 81.8% and 98.1% respectively.

Pulsatile control of rotary blood pumps: Does the modulation waveform matter?
TL;DR: A synchronized pulsing rotary blood pump offers a simple and powerful control modality for heart unloading and provides pulsatile hemodynamics, which is more physiologic than continuous blood flow and may be useful for perfusion of the other organs.

ECG data compression with time-warped polynomials
TL;DR: The author presents a new adaptive compression method for ECGs that achieves a high-quality approximation at less than 250 bits/s and the corresponding rates for other transform based schemes (the DCT and the DLT) are always higher.

An Automated Strategy for Early Risk Identification of Sudden Cardiac Death by Using Machine Learning Approach on Measurable Arrhythmic Risk Markers
TL;DR: The present results show that both the automated classifier and the integrated SCDI can predict the SCD up to 30 minutes earlier, and that these predictions could be more practical and efficient if applied in portable smart devices with real-time requirements in hospital settings or at home.

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.
