Atrial fibrillation: to map or not to map?

Isolation of the pulmonary veins may be an effective treatment modality for eliminating atrial fibrillation (AF) episodes but unfortunately not for all patients. When ablative therapy fails, it is assumed that AF has progressed from a trigger-driven to a substrate-mediated arrhythmia. The effect of radiofrequency ablation on persistent AF can be attributed to various mechanisms, including elimi...

A Novel Approach to Background Subtraction Using Visual Saliency Map

Generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. Using visual saliency map for modelling gives important information for understanding in many applications. In this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. The proposed technique i...

To Pace Or Not To Pace! — Prevention Of Atrial Fibrillation After Coronary Artery Bypass Surgery

Atrial fibrillation (AF) is a very undesirable, but unfortunately a common arrhythmia following coronary artery bypass graft (CABG) surgery, occurring in up to 40% of patients1. There is an increase in hospital stay2 and adds to the overall cost of the surgery. Atrial fibrillation occurrence may identify a subset of patients with reduced survival3. Prevention of AF therefore would have a signif...
