Background: Implanting a ventricular demand leadless pacemaker (VVI-LPM) for patients
with non-atrial fibrillation (AF) bradyarrhythmias such as sick sinus syndrome (SSS) or high …

Background Patients with atrial fibrillation (AF) who are not suitable for longterm
anticoagulant therapy undergo percutaneous left atrial appendage closure (LAAC). The …

Aims The HINODE study aimed to analyse rates of mortality, appropriately treated ventricular
arrhythmias (VA), and heart failure in Japanese patients and compared with those in …

Introduction The incidence of arrhythmia in heart failure with non-reduced ejection fraction
(HFnon-rEF) in patients who have a history of hospitalisation is unclear. The aim of this study …

Background: There are limited data about predictors of atrial fibrillation (AF) recurrence after
totally thoracoscopic ablation (TTA). This study investigated the clinical implication of left …

Background: The randomized controlled VOLCANO trial demonstrated comparable 1-year
rhythm outcomes between patients with and without ablation targeting low-voltage areas …

Background High percent ventricular pacing maximizes cardiac resynchronization therapy
(CRT) response. An effective CRT algorithm classifies each left ventricular (LV) pace as …

Background Oxidative stress is associated with atrial fibrillation recurrence following
catheter ablation. Urinary isoxanthopterin (UIXP) is one of the noninvasive markers which …

Introduction Diagnosis of outflow tract ventricular arrhythmia (OTVA) localization by an
electrocardiographic complex is key to successful catheter ablation for OTVA. However …

P-wave morphology reflects atrial remodeling and indicates prognosis after radiofrequency
catheter ablation (RFCA) for atrial fibrillation (AF). The impact of p-wave morphology after …
