Epicardial Electrical Activation During Atrial Fibrillation: Looking at the Other Side of the Coin.

High-definition mapping of atrial fibrillation is most commonly performed from the endocardial surface. This report describes an example of a case in which combined mapping of the endocardium and epicardium of the left atrium demonstrated electrical dissociation between the 2 surfaces and implies that endocardial mapping alone may not provide sufficient information.

Hybrid ablation under intraoperative 3D voltage mapping guidance.

Long-standing persistent atrial fibrillation remains a significant therapeutic challenge, often proving to be resistant to treatment with antiarrhythmic medications and transcatheter ablation. Hybrid ablation, which combines a minimally invasive surgical and transcatheter approach, is emerging as a promising treatment option. In this video tutorial, we demonstrate our method of hybrid ablation for long-standing persistent atrial fibrillation using advanced 3D electro-anatomical voltage mapping to guide the ablation process and thereby improve the ultimate effectiveness of the procedure.

Autonomy and Firefighting: Perceived Competence and Stress.

Objective: In workplace settings, autonomy is implicated in employee motivation as well as supervisor autonomy support. As a profession of risk, firefighters may experience greater levels of stress.

Methods: A self-determination paradigm was applied to the firefighter workplace.
