Filter by:This is a prospective pivotal study in patients admitted/visiting the cardiology ward and/or outpatient clinics for various indications. The study will be conducted in two stages. The first stage will comprise a pilot study with 10 subjects, which will be completed and analyzed prior to initiation of the second stage. The two studies are independent and are included in the same protocol for logistical reasons. The second stage of the study, which will include 120 subjects, is pivotal and intended to validate the Gili BioSensor System. Testing procedure will include seating the subject in either a steady chair in front of a table, or in bed with the bedrest raised in front of a cardiac table (or similar). The subject will be seated for 5 minutes to reach a physiological steady state. During this time, the subject will be connected to the reference device according to the manufacturer's guidelines. The investigational device will be placed on a stable surface in front of the subject (table / cardiac table or similar) and will point to the left side of the subject's chest. Both the investigational and reference devices will be temporally synchronized to maintain coordinated recording. Following the 5-minute resting period, both investigational and reference devices will be activated for a comparative recording session to acquire at least 180 seconds (3 minutes) of evaluable data. Each 60-sec interval will be used separately for comparative analyses.
Febrile infants younger than 3 months old present a diagnostic dilemma to the emergency physician. Tension remains between the need for early aggressive intervention among patients with suspected sepsis and the global phenomena of increasing antibiotic resistance. The investigators aim to: (1) To study the association between heart rate variability (HRV) and the presence of a serious infection (SI) among infants younger than 3 months old. The investigators hypothesize that a reduced HRV is associated with the presence of SI. (2) To compare HRV between febrile infants < 3 months with non-febrile infants. The investigators hypothesize that the variability will be reduced in febrile infants with SIs when compared to non-febrile well infants, but not among febrile infants without SIs when compared to non-febrile well infants. (3) To study if HRV will provide incremental diagnostic information over current triage tools.
Transcutaneous electric nerve stimulation (TENS) is widely used for the treatment of adhesive capsulitis, nevertheless, its potential impact on heart physiology has not been well established. The investigator explored if TENS at shoulder region affect heart rhythm and the machinery involved. Subjects were stratified into groups received sham stimulation (TENS-S) and TENS on either the right (TENS-R) or left (TENS-L) shoulder. A built-in waveform for treating adhesive capsulitis with a maximal tolerable intensity below the pain threshold was applied to subjects form a commercial TENS equipment for 5 min. The electrocardiogram (ECG) and heart rate (HR) were continuously recorded and the ECG was off-line transferred into power spectrum for analysis.
Exercise training is a cornerstone for the prevention and treatment of metabolic disorders and associated cardiometabolic complications such as type 2 diabetes mellitus (T2D) and hypertension. Similar to the beneficial health effects after performing conventional continuous exercise modalities, high intensity interval training (HIIT) has been reported as an effective alternative exercise-modality to improve glucose homeostasis in both prediabetes subjects and individuals with T2D diagnosed. In this regard, although multiple HIIT-based interventions commonly report acute and long term benefits on body composition, cardiorespiratory fitness and insulin sensitivity in metabolically compromised subjects, little is known about the acute cardiovascular response (i.e., at heart rate level) during HIIT in subjects with different glucose control. HIIT is described as performing brief periods of exercise at vigorous or maximal intensity, interspersed with inactive or low intensity recovery phases of variable duration. In order to characterize different HIIT-based protocols, exercise intensity is usually defined as relative percentages of individual maximal cardiorespiratory fitness (VO2max) or relative maximal power output values. Nevertheless, the need for specific technological equipment to assess these parameters usually limit the prescription and recommendations of HIIT in clinical settings and other public health contexts at massive level. Additionally, the use of self-perceived exertion scales and heart rate (HR) variations upon HIIT have been demonstrating to be accessible and feasible strategies to regulate exercise intensity during HIIT. For example, it was reported that HR and self-perceived exertion scores increased progressively in T2D subjects, parallel to the oxygen consumption rate throughout an acute HIIT session performed on cycle ergometer. Consequently, it is conceivable to hypothesize that determining HR variations during HIIT might optimize the recommendation of this training methodology in metabolically compromised subjects as those at risk or with T2D diagnosed. Therefore, the aim of the present study was To describe and compare the acute heart rate changes in response to an incremental maximal exercise test and a single HIIT session between normoglycaemic (NG), prediabetes (Pre-T2D) and type 2 diabetes mellitus (T2D) subjects.
Implantation with left ventricular assist device (LVAD) in patients with end-stage heart failure (HF) leads to improvements in survival and quality of life, however, work capacity remains disappointingly low, at half of the expected value. Complex central and peripheral hallmarks of heart failure attribute to the continued work intolerance, to which heart rate may be a contributing factor. The purpose of this study is to clarify the impact of heart rate (by means of pacing) on work capacity (measured as peak oxygen uptake) in LVAD recipients.
In a collaborative project between University Hospital Southampton NHS Trust and the University of Southampton, the investigators have developed a wearable, mobile, non invasive, low-cost, continuous respiratory rate monitor device called a capaciflector. This study will be the first ever study undertaken to attempt to measure the respiratory rate and heart rate on patients using a capaciflector. Investigators will evaluate whether the correlation between the capaciflector's measurements of respiratory rate and heart rate when compared with the gold standard pneumotachometer and electrocardiogram respectively is high enough to promote its potential future use within a device for clinical practice.
This proposal describes the evaluation of a CE-marked, FDA cleared vital signs Surveillance Monitoring system in a paediatric outpatient population in KK Women's and Children's Hospital ("KKH"), the main tertiary women and children hospital in Singapore. User acceptance of Aingeal and the Surveillance System will be considered within the clinical settings.

Ryder Heart is an exploratory study of the heart rate variations of golf fans during the 2018 edition of the Ryder Cup. The main objective is to evaluate the impact of stress and strong emotions on heart rate variations and the occurrence of rhythmic anomalies in golf fans during this high-level golf competition. Such data are actually poorly described in medical and scientific literature.
This a randomized, double blind, placebo controlled, crossover design study which measures the effect of an available thermogenic dietary supplement on resting energy expenditure (REE), blood pressure and heart rate, and mood changes in moderate caffeine consumers. Participants will complete baseline measurements then ingest one of three pills. Once the pill is ingested, subjects will complete four REEs along with heart rate and blood pressure and appropriate questionnaires. Participants will return two more times, each after a one week washout period, and complete the same protocol with the remaining supplements.
