ABSTRACT
A venous insufficiency, to which the deep veins of the lower human extremities are particularly susceptible, can lead to serious diseases, such as a deep vein thrombosis (DVT) with subsequent risks of severe implications, e.g. pulmonary embolism or a post-thrombotic syndrome (PTS) [6]. The current standard procedure to diagnose venous insufficiency is performed exclusively in medical offices and hospitals in the form of in-patient treatments with special medical equipment. This hurdle for the patient, combined with the often diffuse symptoms of venous insufficiency [7], may lead to a late discovery of diseases such as DVTs and increases the risk of secondary diseases as well as treatment costs [3]. To address these issues, we propose a novel method for continuous monitoring of the current venous function by adapting the Light Reflection Rheography (LLR) and using low-cost wearable sensor technology and a smartphone app, aiming to deliver critical early stage information about pathological changes of the blood flow in the lower limbs.

A novel method to measure blood flow in the popliteal vein using ultrasound Doppler system
i-CREATe '14: Proceedings of the international Convention on Rehabilitation Engineering & Assistive TechnologyDeep vein thrombosis is a serious medical condition, especially in stroke patients, where the major reason can be attributed to venous stasis [8] due to lack of ankle exercises which causes blood clots to form in the veins. This study aims to investigate ...
Atrial fibrillation signatures on intracardiac electrograms identified by deep learning
Abstract BackgroundAutomatic detection of atrial fibrillation (AF) by cardiac devices is increasingly common yet suboptimally groups AF, flutter or tachycardia (AT) together as ‘high rate events’. This may delay or misdirect ...
Highlights- Automatic detection of atrial fibrillation often groups AF with flutter or tachycardia, which may delay or misdirect therapy.
Measurements of the left atrium and pulmonary veins for analysis of reverse structural remodeling following cardiac ablation therapy
Rationale and objectivesGeometric analysis of the left atrium and pulmonary veins is important for assessing reverse structural remodeling following cardiac ablation therapy. Most volumetric analysis techniques, however, require laborious manual tracing ...
