Structural and functional characteristics of myocard in patients with different forms of atrial fibrillation

Zaporožskij Medicinskij Žurnal, 2015
Aim. To study structural and functional characteristics of myocard in patients with different forms of atrial fibrillation. Atrial fibrillation is the most prevalent arrhythmia in clinical practice.

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Cryoballoon Ablation for Atrial Fibrillation

Indian Pacing and Electrophysiology Journal, 2012
Focal point-by-point radiofrequency catheter ablation has shown considerable success in the treatment of paroxysmal atrial fibrillation. However, it is not without limitations.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Computational modelling of the pro‐ and antiarrhythmic effects of atrial high rate‐dependent trafficking of small‐conductance calcium‐activated potassium channels

The Journal of Physiology, EarlyView.
Abstract figure legend Small‐conductance calcium‐activated potassium (SK) channels are important for atrial repolarization and can be targeted for atrial‐specific antiarrhythmic treatments. We developed a computational model with a calcium sensor to study the effects of increased pacing rate (5 Hz), which enhances SK‐channel gating and forward ...

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]

, 2004
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.
