Detection of atrial fibrillation in persons aged 65 years and above using a mobile electrocardiogram device.

Background: Untreated atrial fibrillation (AF) often results in increased morbidity and mortality. Opportunistic AF screening in persons aged ≥ 65 years is recommended to identify patients with AF in order to prevent AF-related complications.

Objective: The aim of this study was to assess the feasibility of screening persons for AF with the Kardia mobile electrocardiogram device (MED) and to determine the percentage of newly detected AF cases by selective population screening in the Netherlands.

Radiofrequency catheter ablation of left ventricular outflow tract tachycardia with the assistance of the CartoSound system.

Catheter ablation of left ventricular outflow tract tachycardia (LVOTT) holds the risk of complications, if foci are located close to the coronary artery orifices. The use of an accurate three-dimensional electro-anatomic approach is necessary to avoid ablation in the coronaries. We report a case in which we demonstrate the value of the CartoSound system, in the ablation of LVOTT.
