TL;DR: In this paper, structural changes in both atria and their association with recurrence of atrial fibrillation after radiofrequency catheter ablation (RFCA) were assessed.

TL;DR: Anemia was associated with an increased risk of SCA even after accounting for concomitant conditions in a South Korean nationwide cohort, and a negative correlation between QTc interval and Hb level was observed in men and women.

TL;DR: The paced QTc interval appears to be a more useful marker in predicting bad prognosis than does the intrinsic QTC interval in patients with indications for a permanent pacemaker.

TL;DR: OAT in patients with nonvalvular atrial fibrillation with histories of gastrointestinal ulcer made no difference in the composite end point compared to absence of OAT, and in OAT+ patients, maintaining an optimal international normalized ratio reduced the Composite end point, and the confirmation of ulcer healing reduced the incidence of bleeding.

TL;DR: In patients with L-PeAF, prolonged PS-SNRT is an independent predictor of clinical recurrence of AF after RFCA, but not closely associated with electro-anatomical remodeling of LA.
