Spontaneous initiation of atrial fibrillation by ectopic beats originating in the pulmonary veins.
New England Journal of Medicine, 1998 BACKGROUND Atrial fibrillation, the most common sustained cardiac arrhythmia and a major cause of stroke, results from simultaneous reentrant wavelets. Its spontaneous initiation has not been studied.

Residual Feature Pyramid Network for Enhancement of Vascular Patterns [PDF]
in Proceedings of the IEEE/CVF Conference on Computer Vision and
Pattern Recognition (CVPR) Workshops, 2022, pp. 1588-1595, 2023 The accuracy of finger vein recognition systems gets degraded due to low and uneven contrast between veins and surroundings, often resulting in poor detection of vein patterns. We propose a finger-vein enhancement technique, ResFPN (Residual Feature Pyramid Network), as a generic preprocessing method agnostic to the recognition pipeline.
