Beat-to-beat interval measurement in the electrocardiogram
Medical and Biological Engineering and Computing, 1985A method of measuring online interval durations between different waves in the electrocardiogram is presented. After preprocessing two signals, data segments containing the wave segments of interest are sampled. The detection of time reference points for these waveforms is accomplished in a separate recognition phase (of prime importance for the ...

Beat‐to‐beat oscillations in pulse pressure
Clinical Physiology and Functional Imaging, 2004SummaryWe compared 5‐min standard deviations (SD) and frequency domain measures of beat‐to‐beat pulse pressure (PP) variability with those of RR‐interval, systolic (SBP) and diastolic (DBP) blood pressure variabilities, and with cross‐spectral baroreflex sensitivity (BRS) in a population‐based sample of 150 healthy individuals, aged 35–64 years.

Three beat-to-beat cardiotachometer designs
Medical & Biological Engineering & Computing, 1981The paper introduces three beat-to-beat cardiotachometers in addition to the four types described by MASON and SHOUP (1979). Two systems are semi-analogue and one all-digital. A detailed description of the principles of operation including block diagrams is given.

Catheterization and Cardiovascular Interventions
Key points Technical advancements in devices and the development of techniques to optimize valve implantation have been the cornerstone of improvement in outcomes of TAVR. While device success and the rate of paravalvular leak have decreased over time, the rate of permanent pacemaker implantation following self‐expanding valve systems remains high ...
