Incidence and Determinants of Spontaneous Cardioversion of Early Onset Symptomatic Atrial Fibrillation

Medicina, 2022
Atrial fibrillation (AF) is the most frequent chronic arrhythmia worldwide, and it is associated with significant morbidity and mortality, making it a considerable burden both to patients and the healthcare system.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Left atrial mechanical remodelling assessed as the velocity of left atrium appendage wall motion during atrial fibrillation is associated with maintenance of sinus rhythm after electrical cardioversion in patients with persistent atrial fibrillation.

PLoS ONE, 2020
The velocity of left atrium appendage (LAA) wall motion during atrial fibrillation (AF) is a potential marker of mechanical remodelling. In this study, we investigated whether the velocity of LAA wall motion during AF predicted the success of electrical ...

Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

NT-proBNP predicts maintenance of sinus rhythm after electrical cardioversion

, 2015
BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia. NT-proBNP is a fragment of the prohormone brain natriuretic peptide. Previous studies indicate that increased levels of NT-proBNP are associated with higher recurrence rates of AF after ...

Right atrial volume index and right atrial volume predict atrial fibrillation recurrence: A meta-analysis.

PLoS ONE
BackgroundAtrial volume index and atrial volume have recently been identified as predictors of atrial fibrillation (AF) recurrence following electrical cardioversion or radiofrequency ablation. However, most studies have reported the relationship between

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...
