Development of a standard fall data format for signals from body-worn sensors The FARSEEING consensus

Kamiar Aminian

Objective measurement of real-world fall events by using body-worn sensor devices can improve the understanding of falls in older people and enable new technology to prevent, predict, and automatically recognize falls. However, these events are rare and he ...

Data processing techniques for the characterization of atrial fibrillation

Mathieu Lemay

Atrial fibrillation is the most common sustained cardiac rhythm disturbance, increasing in prevalence with age. During the past 20 years, there has been a 66% increase in hospital admissions related to atrial fibrillation. Neither the natural history of at ...
