Consistency of pacing and metabolic responses during 2000-m rowing ergometry [PDF]

, 2013
PURPOSE: This study investigated the pacing strategy adopted and the consistency of performance and related physiological parameters across three 2000-m rowing-ergometer tests. METHODS: Fourteen male well-trained rowers took part in the study.

Ventricular divergence correlates with epicardial wavebreaks and predicts ventricular arrhythmia in isolated rabbit hearts during therapeutic hypothermia [PDF]

, 2020
INTRODUCTION: High beat-to-beat morphological variation (divergence) on the ventricular electrogram during programmed ventricular stimulation (PVS) is associated with increased risk of ventricular fibrillation (VF), with unclear mechanisms.

Zero-fluoroscopy approach for ablation in Wolf -Parkinson – White syndrome during pregnancy

Heart Vessels and Transplantation, 2022
Paroxysmal supraventricular tachycardias during pregnancy are rare; however, it can be a therapeutic challenge because of limitations about use of antiarrhythmic drug therapy and catheter ablation indication, due to the risk of radiation exposure to the ...

LDL-C/HDL-C is associated with ischaemic stroke in patients with non-valvular atrial fibrillation: a case-control study

Lipids in Health and Disease, 2020
Background This study explored the relationships between the low−/high-density lipoprotein cholesterol ratio (LDL-C/HDL-C) and other clinical indicators and ischaemic stroke (IS) in patients with non-valvular atrial fibrillation (NVAF) in Xinjiang.

Aging‐induced atrial fibrosis in If current change and its effect on atrial fibrillation in dogs

Annals of Noninvasive Electrocardiology, 2022
Background Atrial fibrillation (AF) is a very common type of cardiac arrhythmia that threatens public health. Aging is an independent AF risk factor. However, the mechanism of age‐related AF remains unclear.

Post–Myocardial Infarction Scar With Fat Deposition Shows Specific Electrophysiological Properties and Worse Outcome After Ventricular Tachycardia Ablation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Fat deposition (FD) is part of the healing process after myocardial infarction. The characteristics of FD and its impact on the outcome in patients undergoing ventricular tachycardia (VT) ablation have not been thoroughly studied.

Can pacing self-management alter physical behaviour and symptom severity in chronic fatigue syndrome? : a case series [PDF]

, 2009
Given the lack of evidence in support of pacing self-management for patients with chronic fatigue syndrome (CFS), we examined whether physical behavior and health status of patients with CFS Would improve in response to a pacing self-management program ...

Elevated β1-Adrenergic Receptor Autoantibody Levels Increase Atrial Fibrillation Susceptibility by Promoting Atrial Fibrosis

Frontiers in Physiology, 2020
ObjectiveBeta 1-adrenergic receptor autoantibodies (β1ARAbs) have been identified as a pathogenic factor in atrial fibrillation (AF), but the underlying pathogenetic mechanism is not well understood. We assessed the hypothesis that elevated β1ARAb levels

Sudden Cardiac Death in Athletes: From the Basics to the Practical Work-Up

Medicina, 2021
Sudden cardiac death in athletes is a relatively rare event, but due to the increasing number of individuals practicing high-performance sports, in absolute terms, it has become an important issue to be addressed.

Indeterminacy of Spatiotemporal Cardiac Alternans

, 2008
Cardiac alternans, a beat-to-beat alternation in action potential duration (at the cellular level) or in ECG morphology (at the whole heart level), is a marker of ventricular fibrillation, a fatal heart rhythm that kills hundreds of thousands of people ...
