Validity of Telemetric-Derived Measures of Heart Rate Variability: A Systematic Review

Heart rate variability (HRV) is a widely accepted indirect measure of autonomic function with widespread application across many settings. Although traditionally measured from the ‘gold standard’ criterion electrocardiography (ECG), the development of wireless telemetric heart rate monitors (HRMs) extends the scope of the HRV measurement. However, the validity of telemetric-derived data against the criterion ECG data is unclear. Thus, the purpose of this study was twofold: (a) to systematically review the validity of telemetric HRM devices to detect inter-beat intervals and aberrant beats; and (b) to determine the accuracy of HRV parameters computed from HRM-derived inter-beat interval time series data against criterion ECG-derived data in healthy adults aged 19 to 62 yrs. A systematic review of research evidence was conducted. Four electronic databases were accessed to obtain relevant articles (PubMed, EMBASE, MEDLINE and SPORTDiscus. Articles published in English between 1996 and 2016 were eligible for inclusion. Outcome measures included temporal and power spectral indices (Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology (1996). The review confirmed that modern HRMs (Polar® V800™ and Polar® RS800CX™) accurately detected inter-beat interval time-series data. The HRV parameters computed from the HRM-derived time series data were interchangeable with the ECG-derived data. The accuracy of the automatic in-built manufacturer error detection and the HRV algorithms were not established. Notwithstanding acknowledged limitations (a single reviewer, language bias, and the restricted selection of HRV parameters), we conclude that the modern Polar® HRMs offer a valid useful alternative to the ECG for the acquisition of inter-beat interval time series data, and the HRV parameters computed from Polar® HRM-derived inter-beat interval time series data accurately reflect ECG-derived HRV metrics, when inter-beat interval data are processed and analyzed using identical protocols, validated algorithms and software, particularly under controlled and stable conditions

HYBRID: TRANSDISCIPLINARY: TRANSFORMATIVE:

This document brings together materials produced for and during a PhD by Designstudy and workshop day held at Leeds College of Art on May 14th 2015. This day was dedicated to exploring multiple possibilities of innovatively disseminating practice based design research. Twenty-nine participants contributed to the day with a 5 minute presentation of one instance of dissemination of their research, reflecting on what they did, what worked and what did not and why. These presentations, and the practices at their core, where the basis for our collective exploration. This journal has been produced on May 14th 2015 as an experiment in how knowledge generated through an event can be disseminated instantly - in a form that allows for unpolished and fresh thoughts to be circulated. The Instant Journals pages consist of each participants biography, their research topic and a question that they were looking to explore on the day. This is followed by a page where they had one hour at the end of the day to document a response to this original question

HYBRID: TRANSDISCIPLINARY: TRANSFORMATIVE: An instance of travelling in practice-led research: Talk in 5 minutes

HYBRID: TRANSDISCIPLINARY: TRANSFORMATIVE An instance of travelling in practice-led research: Talk in 5 minutes Hybrid practices with (or without) digital or interactive technologies can transport us to unexpected new spaces and places; On our nomadic practitioner journeys we transform: move, change and coevolve through thinking and experimenting with tools, creating objects, artefacts, experiences, new ways or methods, languages, and production paradigms. This five minute reflexive talk; explores how becoming more open and receptive to co-creative approaches of this nature can positively enhance, shift, transform and transcend; us as practitioners, our approaches, and methods and the disciplines themselves now and in the future. I have collaborated with colleagues from within School of Art, Design & Architecture and in School of Music, Media and Humanities and external partners from outside the University on various phases of an evolving AHRC/EPSRC research project focused on the 3D Environments, acoustics modelling, animation and music of prehistory since 2009. This practice led trans-disciplinary experimental immersive acoustic research is concerned with understanding and exploring the ritual praxis of Neolithic makers of Stonehenge. The multiplexity of unanticipated experiences and un-expected data we sourced, created, developed and disseminated together, is shared in this talk at PhD by Design. During the progressive phases of this practice-led transdisciplinary research, we, as practitioners: artists, designers, theorists, makers, musicians, historians, curators.., collectively gained a deeper understanding into how humans: then and now, and the technologies we make, can generate a unique transformative contribution to the dissolving of physical, disciplinary and cultural boundaries

Student perceptions of a healthy university

As complex environments within which individuals and populations operate, universities present important contexts for understanding and addressing health issues. The healthy university is an example of the settings approach, which adopts a whole system perspective, aiming to make places within which people, learn, live, work and play supportive to health and wellbeing. The UK Healthy Universities Network has formulated an online toolkit, which includes a self-review tool, intended to enable universities to assess what actions they need to take to develop as a healthy university. This paper presents findings from consultative research undertaken with students from universities in England, Scotland and Wales, which explored what they believe represents a healthy university. Methods Student surveys and focus groups were used to collect data across eleven universities in England, Scotland and Wales. A priori themes were used to develop our own model for a healthy university, and for the thematic coding phase of analysis. Findings A healthy university would promote student health and wellbeing in every aspect of its business from its facilities and environment through to its curriculum. Access to reasonably priced healthy food and exercise facilities were key features of a healthy university for students in this study. The Self Review Tool has provided a crucial start for universities undertaking the journey towards becoming a healthy university. In looking to the future both universities and the UK Healthy Universities Network will now need to look at what students want from their whole university experience, and consider how the Self Review Tool can help universities embrace a more explicit conceptual framework. Conclusion The concept of a healthy university that can tailor its facilities and supportive environments to the needs of its students will go some way to developing students who are active global citizens and who are more likely to value and prioritise health and wellbeing, in the short and long term through to their adult lives

Comparison of whole house heat loss test methods under controlled conditions in six distinct retrofit scenarios

The accurate assessment of buildings to assess their performance across a range of parameters is an essential part of understanding both new and retrofit buildings. The growing understanding of the performance gap in terms of its assessment and characterisation relies on effective methods of analysis. Here, we evaluate an experimental whole house method, known as QUB. As with many whole building approaches the method establishes heat loss through transmission and ventilation losses. This study compares QUB against an alternative, established, whole house test known as coheating. It was applied in a whole house test facility under controlled conditions. The test property, a solid wall pre-1919 UK archetype, was retrofit using a set of commercially available products and then the retrofit was removed in stages. At each of these stages a QUB test, which commonly takes one night, and coheating test, which can take few weeks, were applied. The objective of the study was to provide a comparison between the new method and more established method in terms of accuracy. The two methods showed close agreement in terms of results, suggesting that the quicker test has great potential as a more practical and economic test. There were higher levels of uncertainty with the QUB method due to shorter measurement periods. The lack of full boundary conditions within the test facility should be considered a limitation in applying the findings directly to the field. However, this study indicates the potential for QUB in validating performance, warranting further investigation
