Background: Prediction of the chamber of origin in patients with outflow tract ventricular arrhythmias (OTVA) remains challenging. A clinical risk score based on age, sex and presence of hypertension was associated with a left ventricular outflow tract (LVOT) origin. We aimed to validate this clinical score to predict an LVOT origin in patients with OTVA. Methods: In a two‐center observational cohort study, unselected patients undergoing catheter ablation (CA) for OTVA were enrolled. All procedures were performed using an electroanatomical mapping system. Successful ablation was defined as a ≥80% reduction of the initial overall PVC burden after 3 months of follow‐up. Patients with unsuccessful ablation were excluded from this analysis. Results: We included 187 consecutive patients with successful CA of idiopathic OTVA. Mean age was 52 ± 15 years, 102 patients (55%) were female, and 74 (40%) suffered from hypertension. A LVOT origin was found in 64 patients (34%). A score incorporating age, sex and presence of hypertension reached 73% sensitivity and 67% specificity for a low (0–1) and high (2–3) score, to predict an LVOT origin. The combination of one ECG algorithm (V2S/V3R‐index) with the clinical score resulted in a sensitivity and specificity of 81% and 70% for PVCs with R/S transition at V3. Conclusion: The published clinical score yielded a lower sensitivity and specificity in our cohort. However, for PVCs with R/S transition at V3, the combination with an existing ECG algorithm can improve the predictability of LVOT origin. [ABSTRACT FROM AUTHOR]

4. Google Apps as an alternative to Microsoft Office in a multinational company: the GAPS project

- Abstract
A large multinational Company is launching the GAPS Project to assess the suitability of Google Apps as an alternative to the current email, collaboration and office toolset. In order to make a decision, the company needs recommendations based on a complete project assessing the Google Apps offering, taking into account the company’s specificities. The company currently uses Microsoft Office with Exchange. Identified problems include the cost of licenses, their dependency on Microsoft, the complex licensing model, and concerns about the use of the current solutions by the contractors. The GAPS Project describes the steps that the company should follow. In particular, a pilot phase should be conducted with users representing the diversity of the company’s users in terms of geographical location and business lines. Success criteria have been defined. They include contractual aspects, business requirements, financial aspects, support, operational aspects, security, and user satisfaction. Pilot results will provide a classification of the company users according to the ability of Google Apps to provide solutions corresponding to their requirements. Google Apps Premier Edition is a web application suite for businesses. It offers an email storage capacity of 25 GB per user and a Service Level Agreement describing 99.9% uptime guarantee. Advantages for the company are new business opportunities, such as the real time editing feature and the ability to share a document with an external partner. The messaging service allows the company users to save time, thanks to the large storage capacity and to the well organized mailboxes. The licenses are less expensive than those of Microsoft. Google Apps can be made available to the contractors, as they don’t require tools other than a messaging service. However, advanced users would suffer from the lack of functionality and from compatibility issues, especially when opening Microsoft Office documents with rich content. Frequent trav
