Paroxysmal atrial fibrillation in cryptogenic stroke

Therapeutics and Clinical Risk Management, 2011
Paroxysmal atrial fibrillation (PAF) is perhaps the most underdiagnosed mechanism of apparent cryptogenic stroke (CS). Various studies have shown that increasing the duration of monitoring can increase the diagnosis of PAF in CS.We compared demographic and risk factors for ischemic stroke across different TOAST (Trial of ORG 10172 in Acute Stroke ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Atrial late potentials: paroxysmal supraventricular tachycardia versus paroxysmal atrial fibrillation

International Journal of Cardiology, 1993
The atrial signal averaged electrocardiogram has been used to detect patients at risk for paroxysmal atrial fibrillation but not yet for paroxysmal supraventricular tachycardia. The P-wave-triggered signal-averaged electrocardiogram, during sinus rhythm, was obtained from 97 subjects divided in groups as follows: 30 controls (Group C), 38 patients with

Paroxysmal atrial fibrillation [PDF]

QJM, 2001
There has been a tendency to treat paroxysmal atrial fibrillation (PAF) in a similar way to sustained AF, but treatment objectives may be very different. We discuss current definitions, epidemiology, pathophysiology and natural history of PAF, and review evidence for its treatment and management.

Paroxysmal Atrial Fibrillation in Sleep [PDF]

Sleep, 1997
Thirty-eight patients with lone paroxysmal atrial fibrillation (PAF) were monitored during spontaneous sleep. The starts of 111 episodes of atrial fibrillation (AF) occurred in 12 patients. Statistical analysis failed to disclose significant differences in the number of starts per hour between wakefulness and the different sleep stages. Heart rate (HR)

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]

, 2006
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Catheter ablation of atrial fibrillation : radiofrequency catheter ablation for redo procedures after cryoablation [PDF]

, 2013
Aim: To evaluate the effectiveness of two different strategies using radiofrequency catheter ablation for redo procedures after cryoablation of atrial fibrillation. Methods: Thirty patients (paroxysmal atrial fibrillation: 22 patients, persistent atrial

A preliminary assessment of the effects of ATI-2042 in subjects with paroxysmal atrial fibrillation using implanted pacemaker methodology [PDF]

, 2009
Aims ATI-2042 (budiodarone) is a chemical analogue of amiodarone with a half life of 7 h. It is electrophysiologically similar to amiodarone, but may not have metabolic and interaction side effects.

Prevalence and determinants of atrial fibrillation progression in paroxysmal atrial fibrillation

Heart, 2022
Objective Atrial fibrillation (AF) often progresses from paroxysmal AF (PAF) to more permanent forms. To improve personalised medicine, we aim to develop a new AF progression risk prediction model in patients with PAF.

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...
