Article Synopsis
  • - The study assessed a new automated system that localizes the origin of ventricular tachycardia (VT) using a 12-lead ECG, aiming to improve the process of catheter ablation.
  • - The system's accuracy was evaluated across 21 ablation procedures in 19 patients, with localization errors calculated from known reference sites to estimated sites, revealing an accuracy of 3.5 mm with patient-specific adjustments.
  • - The results indicated that the localization system achieved an overall accuracy within 10 mm, suggesting it has potential clinical applications for managing VT.

Background: Cardiac rehabilitation (CR) intervention programs are currently not part of management in patients with atrial fibrillation (AF). We sought to determine the effect of CR compared with a specialized AF clinic (AFC) and usual care on outcomes in patients with AF.

Methods: This was a single-centre retrospective cohort study that was carried out using 3 databases: the Hearts in Motion database (2010-2014), prospectively collected data in an AFC (2011-2014), and a retrospective chart review for patients in usual care (2009-2012).

Background: Patients with ventricular tachycardia (VT) postmyocardial infarction (MI) are a higher risk group with significant morbidity and mortality. We examined the impact of prior coronary revascularization on clinical outcomes in patients with ischemic cardiomyopathy and VT.

Methods: The VANISH trial randomized 259 patients with prior MI and antiarrhythmic drug-refractory VT to receive escalated medical therapy or catheter ablation.
