Context HCM is commonly associated with AF. Current guidelines for AF management omit
detailed advice for HCM because of a lack of clinical prediction tools that estimate the risk of …

BACKGROUND: Atrial fibrillation (AF) is a common cardiac arrhythmia that increases the risk
of thromboembolic events. Anticoagulation therapy to prevent AF-related stroke has been …

P-wave dispersion is defined as the difference between the maximum and the minimum P-
wave duration recorded from multiple different-surface ECG leads. It has been known that …

Background Early recurrence of atrial fibrillation (ERAF) and delayed cure are commonly
observed after atrial fibrillation (AF) ablation. The purpose of this study was to determine the …

Background: Atrial fibrillation (AF) is the most common pathological arrhythmia, and its
complications lead to significant morbidity and mortality. However, patients with AF can often …

Background Changes in P wave parameters after circumferential pulmonary vein isolation
(CPVI) have been previously identified. In this study, we aimed to determine the changes in …

Background: Atrial fibrillation is a frequent arrhythmia in patients undergoing hemodialysis.
The consequences of hemodialysis on P wave durations and P wave dispersion have not …

Introduction Obstructive sleep apnea syndrome (OSAS) is associated with autonomic
dysfunction, whereas increased heart rate (HR), HR recovery time (HRR-1), QT-corrected …

Background The electrical activity of atria can be demonstrated by P waves on surface
electrocardiogram (ECG). Atrial electromechanical delay (AEMD) measured with tissue …

Background: Identification of patients at risk for PAF recurrence after AP ablation is important
because of the necessity for additional therapies. Objectives: To determine whether …
