A perspective on automated rapid eye movement sleep assessment

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Rapid eye movement sleep is associated with distinct changes in various biomedical signals that can be easily captured during sleep, lending themselves to automated sleep staging using machine learning systems. Here, we provide a perspective on the critical characteristics of biomedical signals associated with rapid eye movement sleep and how ...

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

open access: yesJournal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

Non-valvular atrial fibrillation and stroke : implications for management [PDF]

open access: yes, 1995
Nonvalvular Atrial Fibrillation is more prevalent with increasing age. It is associated with a six-fold excess risk of stroke; and a cumulative lifetime stroke risk of 35%. 15% of ischaemic strokes are directly attributable to it.

Transcriptomic Remodeling of Pulmonary Vein Sleeves Suggests a Role in Atrial Arrhythmogenesis in Thoroughbred Horses

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
Myocardial sleeves of the pulmonary veins in racehorses with paroxysmal atrial fibrillation exhibit upregulated pathways associated with tissue structure remodeling. Pathways related to the extracellular matrix and cellular components differ significantly from those in healthy horses.

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

open access: yes, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

Efficacy and Safety of the Sync‐AV II Temporary Cardiac Pacing Catheter (EASY II Trial)

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Cardiac pacing is crucial for patients with hemodynamically unstable bradyarrhythmias. For most indications, transvenous pacemakers are used to pace the right ventricle, causing atrioventricular dyssynchrony, which may lead to significant hemodynamic compromise.

Electrophysiological Mechanisms of Atrial Flutter [PDF]

open access: yes, 2006
Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about
