Conventional QT variability measurement vs. template matching techniques: comparison of performance using simulated and real ECG. by Mathias Baumert, Vito Starc, Alberto Porta

“…Increased beat-to-beat variability in the QT interval (QTV) of ECG has been associated with increased risk for sudden cardiac death, but its measurement is technically challenging and currently not standardized. …”

Stochastic models of ion channel dynamics and their role in short-term repolarisation variability in cardiac cells by Dangerfield, CE

“…We illustrate the potential power of this method by incorporating it into a state-of-the-art canine cardiac cell electrophsyiology model so as to explore the effects of stochastic ion channel behaviour on beat-to-beat variability. The stochastic models presented in this thesis fulfil an important role in elucidating the effects of stochastic ion channel behaviour on beat-to-beat variability, a potentially important biomarker of arrhythmic risk.…”

What makes a rhythm complex? The influence of musical training and accent type on beat perception. by Fleur L Bouwer, J Ashley Burgoyne, Daan Odijk, Henkjan Honing, Jessica A Grahn

“…Accents are expected to occur on the beat: when accents are "missing" on the beat, the beat is more difficult to find. However, it is unclear whether accents occurring off the beat alter beat perception similarly to missing accents on the beat. …”

A Hybrid EMD-Kurtosis Method for Estimating Fetal Heart Rate from Continuous Doppler Signals by Haitham M. Al-Angari, Yoshitaka Kimura, Leontios J. Hadjileontiadis, Leontios J. Hadjileontiadis, Ahsan H. Khandoker

“…The proposed EMD-kurtosis method is more robust than AF in low signal-to-noise ratio cases and can be used in a hybrid system to estimate beat-to-beat intervals from DUS. Further analysis to reduce the estimated beat-to-beat variability from the EMD-kurtosis method is needed.…”

Unobtrusive Nocturnal Heartbeat Monitoring by a Ballistocardiographic Sensor in Patients with Sleep Disordered Breathing by Matthias Daniel Zink, Christoph Brüser, Björn-Ole Stüben, Andreas Napp, Robert Stöhr, Steffen Leonhardt, Nikolaus Marx, Karl Mischke, Jörg B. Schulz, Johannes Schiefer

“…As an unobtrusive alternative, we tested a sensor foil for mechanical vibrations to perform a ballistocardiography (BCG) and applied a novel algorithm for beat-to-beat cycle length detection. The aim of this study was to assess the correlation between beat-to-beat cycle length detection by the BCG algorithm and simultaneously recorded ECG. …”
