Transmittance photoplethysmography and pulse oximetry with near infrared laser diodes [PDF]

, 2004
Photoplethysmography and pulse oximetry are widely used techniques for noninvasive monitoring of heart rate and peripheral oxygen saturation. Over the last years we have been working onto the application of near infrared range wavelengths to replace ...

Comparison of Two Pulsed Field Ablation Systems for Atrial Fibrillation: One‐Year Outcomes From a Multicenter Registry

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background While various pulsed field ablation (PFA) systems for atrial fibrillation (AF) ablation have become available in recent years, data comparing long‐term efficacy outcomes remain limited. Purpose To compare long‐term efficacy outcomes of two commercially available PFA systems to perform pulmonary vein isolation (PVI) for AF in a ...

A Comparative Evaluation of Atrial Fibrillation Detection Methods in Koreans Based on Optical Recordings Using a Smartphone

IEEE Access, 2017
This paper evaluated three methods of atrial fibrillation (AF) detection in Korean patients using 149 records of photoplethysmography signals from 148 participants: the k-nearest neighbor (kNN), neural network (NN), and support vector machine (SVM ...

Mobile Health Technology for Atrial Fibrillation Screening Using Photoplethysmography-Based Smart Devices: The HUAWEI Heart study.

Journal of the American College of Cardiology, 2019
BACKGROUND Low detection and nonadherence are major problems in current management approaches for patients with suspected atrial fibrillation (AF). Mobile health (mHealth) devices may enable earlier AF detection, and improved AF management.

On the Vector Space in Photoplethysmography Imaging

CoRR, 2019
We study the vector space of visible wavelength intensities from face videos widely used as input features in Photoplethysmography Imaging (PPGI). Based upon theoretical principles of Group invariance in the Euclidean space we derive a change of the topology where the corresponding distance between successive measurements is defined as geodesic on a ...

Comparative Efficacy of Continuous Versus Patch ECG Monitoring in Detecting Atrial Fibrillation Recurrence Post Catheter Ablation: Insights From the REAL‐AF Registry

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Effective monitoring of atrial fibrillation (AF) recurrence following catheter ablation is crucial for optimizing patient outcomes. Various monitoring strategies exist, but effectiveness comparisons remain underexplored. Objective This study compares the recurrence of atrial arrhythmias detected by continuous versus patch ECG ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Detecting Apnea Events Based on Pulse Oximetry’s Red Photoplethysmography Waveform [PDF]

, 2018
Hypoventilation remains a cause of unexpected hospital death due to limitations in detecting the problem and the associated high false positive alerts, alarm fatigue, and delayed diagnosis.

Recent advancements in deep learning-based remote photoplethysmography methods [PDF]

Health monitoring of an individual is guided by physiological parameters that can be estimated by a photoplethysmography signal using contact-based or contactless approaches. Contactless monitoring, being more advantageous than the contact-based approach,

Middle Managers' Interface Work: Exploring Micro‐Practices for Co‐Adoption of Emerging Ecosystem Value Propositions

Journal of Management Studies, EarlyView.
Abstract Emerging ecosystem value propositions require collective co‐adoption by heterogeneous stakeholders. Focusing on middle managers (MMs) in ecosystem emergence, we introduce the notion of MM interface work: a form of social‐symbolic work comprising discursive, relational, and material micro‐practices within and across cognitive, behavioural ...
