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 ...

Effects of persistent atrial fibrillation-induced electrical remodeling on atrial electro-mechanics – insights from a 3D model of the human atria [PDF]
, 2015 A 3D electromechanical model of the human atria was developed to investigate the effects of AFER on atrial electro-mechanics. Simulations were carried out in 3 conditions for 4states: (i) the control condition, representing the normal tissue (state 1 ...

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 ...

“Wait and See” Approach to the Emergency Department Cardioversion of Acute Atrial Fibrillation
Emergency Medicine International, 2011 Objective. Acute atrial fibrillation often spontaneously resolves. This study aimed to investigate the outcomes and satisfaction of an evidence-based ED protocol employing a “wait and see” approach. Methods.

Electrical cardioversion for atrial fibrillation and flutter [PDF]
Cochrane Database of Systematic Reviews, 2005 Atrial fibrillation increases stroke risk and adversely affects cardiovascular haemodynamics. Electrical cardioversion may, by restoring sinus rhythm, improve cardiovascular haemodynamics, reduce the risk of stroke, and obviate the need for long-term anticoagulation.To assess the effects of electrical cardioversion of atrial fibrillation or flutter on ...

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
