Seismocardiography: Toward heart rate variability (HRV) estimation
2015 IEEE International Symposium on Medical Measurements and Applications (MeMeA) Proceedings, 2015Heart rate variability (HRV), the variation in the beat-to-beat heart rate, is a key indicator of the cardiovascular condition of an individual. The purpose of this study was to cross-validate the beat-by-beat time variations in seismocardiography (SCG) with electrocardiography (ECG) for determining ultra-short term HRV indices.

Estimating Neonatal Oxygen Consumption from Heart Rate
Psychophysiology, 1983ABSTRACTThe relationship between heart rate (HR) and oxygen consumption (V̇o2) has been investigated in a sample of 20 low‐risk, term neonates aged 14–48 hrs. Repeated, simultaneous measurements of HR and V̇o2 were performed on each neonate during each of three epochs ordered by increasing level of activity.

Allometric estimation of metabolic rate from heart rate in penguins
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2005Studies of the relationship between heart rate (f(H)) and rate of oxygen consumption (V(.) (O(2))), which are then used to predict field metabolic rate, frequently fail to incorporate body mass as a predictive variable. This is a potentially important omission in the study of animals whose body mass fluctuates substantially during their annual cycle ...

Fetal baseline heart rate variability estimation
American Journal of Obstetrics and Gynecology, 1979Baseline fetal heart rate variability is an important parameter in the evaluation of fetal status during the intrapartum period. Prior descriptions of variability have largely been either visual-subjective or stochastic in nature. Unfortunately, correlation between the two has not been substantiated.

Stimulus Characteristics Influencing Estimation of Heart Rate
Psychophysiology, 1981ABSTRACTTwo experiments examined the degree to which external stimulus factors and actual HR influence judgments of HR, general accuracy of estimated HR, and self‐perceptions of accuracy. Both studies employed a heartbeat tracking technique while subjects viewed a series of slides (Experiment 1) or were engaged in various tasks (Experiment 2).

Online heart rate estimation in unstable ballistocardiographic records
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010When recording the pressure oscillations of a seated subject two distinct effects are assessed, ample vibrations due to the person's movement, and periodic oscillations of small amplitude due to cardiopulmonary activity, expressed by the ballistocardiogram (BCG). Embedding a pressure sensor in a chair's back or seat allows unobtrusive monitoring of the

Estimation of breathing rate and heart rate from photoplethysmogram
2017 6th International Conference on Electrical Engineering and Informatics (ICEEI), 2017Photoplethysmograph (PPG) is a simple and cost effective method to assess cardiovascular related parameters such as heart rate, arterial blood oxygen saturation and blood pressure. PPG signal consists of not only synchronized heart beats, but also the rhythms of respiration.

Automatic heart rate estimation from painful faces
2014 IEEE International Conference on Image Processing (ICIP), 2014Non-contact measurement of the heart rate is more comfortable than classical methods and can facilitate new applications. However, current approaches are very susceptible to motion. Aiming at overcoming this limitation, we propose a new, more robust approach to estimate the heart rate from a videotaped face.

The heart rate method for estimating metabolic rate: Review and recommendations
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2011Under most circumstances heart rate (f(H)) is correlated with the rate of oxygen consumption (VO(2)) and hence the rate of energy expenditure or metabolic rate (MR). For over 60 years this simple principle has underpinned the use of heart rate to estimate metabolic rate in a range of animal species and to answer questions about their physiology ...
