ECG R-R Interval Estimation
Magnetic resonance imaging (MRI) is a biomedical imaging modality that provides high resolution images and excellent soft tissue contrast [1]. This makes MRI a preferable imaging modality for many applications. One limitation of MRI is slow data acquisition. MRI acquires data in the Fourier domain one point at a time, usually until enough data has been collected to approximately satisfy Nyquist...
متن کاملR-R interval variation in migraine patients
The aim of this study was to evaluate possible cardiovascular autonomic dysfunction in migraine patients with the R-R interval variation (RRIV) measurement, which is an easy and reliable method for the evaluation of parasympathetic function. We studied 71 migraine patients in headachefree intervals (mean age: 31.6±8.9, range 13-57 years; 52 females and 19 males), all without any known heart dis...
متن کاملR-R interval variation and sympathetic skin response in fibromyalgia.
BACKGROUND This study proposed to assess the autonomic nervous system (ANS) functions in fibromyalgia (FM) by using two electrophysiological tests, sympathetic skin response (SSR) and the heart rate variability named R-R interval variation (RRIV). METHODS Sympathetic skin response and RRIV were studied in 29 female patients with FM and 22 healthy age-matched female controls. R-R interval vari...
متن کاملDevelopment of ECG beat segmentation method by combining lowpass filter and irregular R-R interval checkup strategy
We have developed a long-term cardiorespiratory sensor system that includes a wearable sensor probe with adaptive hardware filters and data processing algorithms (Choi & Jiang, 2006, 2008). However, the data processing algorithm proposed for the R–R interval (RRI) information extraction did not work well in the case of ECG signals with baseline shifts or muscle artifacts. Furthermore, many fals...
متن کاملDeterminants and interindividual variation of R-R interval dynamics in healthy middle-aged subjects.
Determinants and intersubject variations of fractal and complexity measures of R-R interval variability were studied in a random population of 200 healthy middle-aged women (age 51 +/- 6 yr) and 189 men (age 50 +/- 6 yr) during controlled conditions in the supine and sitting positions. The short-term fractal exponent (alpha(1)) was lower in women than men in both the supine (1.18 +/- 0.20 vs. 1...
