The study highlights the risks associated with anti-arrhythmic drugs in treating atrial fibrillation (AF). Researchers analyzed data from 674,303 patients with new-onset AF, finding a threefold increased risk for syncope and pacemaker implantation in those prescribed anti-arrhythmic drugs. The risk was higher in older patients and women. The study emphasizes the need for careful evaluation before prescribing these drugs for AF. The findings suggest that bradyarrhythmia events are relatively infrequent but more common in patients on anti-arrhythmic drugs. The study raises questions about extended monitoring for patients on long-term anti-arrhythmic drugs. Limitations include the study's exclusive focus on a Korean population and the lack of detailed patient information due to the nature of the database used.
