Seizure quantification using wearable devices

Epilepsia, EarlyView.
Abstract Accurate assessment of seizure occurrence is central to treatment optimization, risk stratification, and management of epilepsy, yet remains largely dependent on patient‐reported seizure diaries, which are frequently incomplete and unreliable.

Ambulatory electrocardiography in car workers. [PDF]

Occupational and Environmental Medicine, 1978
A previous study in a car assembly plant showed that production-line workers had a lower incidence rate of heart attacks than executive staff. In the present study some major coronary risk factors and 24-hour ambulatory electrocardiograms were investigated in two age-matched samples of 30 middle-aged men drawn from these occupations.

Detection of focal impaired awareness seizures using a biometric shirt

Epilepsia Open, EarlyView.
Abstract Objective In recent years, seizure detection using wearable technology has gained significant attention in research. Most studies, however, have focused on detecting generalized or focal to bilateral tonic–clonic seizures. This study evaluates the feasibility of using a biometric shirt to detect focal impaired awareness seizures (FIAS) by ...

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Multi-centre randomised controlled trial of a smart phone-based event recorder alongside standard care versus standard care for patients presenting to the Emergency Department with palpitations and pre-syncope - the IPED (Investigation of Palpitations in the ED) study: study protocol for a randomised controlled trial

Trials, 2018
Background Palpitations and pre-syncope are together responsible for 300,000 annual Emergency Department (ED) attendances in the United Kingdom (UK). Diagnosis of the underlying rhythm is difficult as many patients are fully recovered on ED arrival; and ...

Heart‐Rate Variability and Its Role in Non‐Cardiac Surgery Perioperative Care: Scoping Review

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Heart rate variability (HRV) is a non‐invasive method of assessing autonomic function. Those with autonomic dysfunction may be at heightened risk of peri‐operative complications due to sympatho‐parasympathetic imbalance. This review summarises the clinical applications of HRV, approaches to how it is measured, and its role in ...

Edge-Deployable Deep Neural Network for Atrial Fibrillation Detection in Ambulatory ECG [PDF]

Ambulatory electrocardiogram (ECG) monitoring is essential for detecting long-term atrial fibrillation (AFib), but it remains challenging due to severe noise, motion artefacts, and signal non-stationarity.
