The ways in which cardiac disease states, extracardiac factors, and abnormal genetic control lead to the arrhythmia are discussed, including the potential therapeutic implications that might arise from an improved mechanistic understanding.Abstract:
Atrial fibrillation (AF) is an extremely common cardiac rhythm disorder that causes substantial morbidity and contributes to mortality. The mechanisms underlying AF are complex, involving both increased spontaneous ectopic firing of atrial cells and impulse reentry through atrial tissue. Over the past ten years, there has been enormous progress in understanding the underlying molecular pathobiology. This article reviews the basic mechanisms and molecular processes causing AF. We discuss the ways in which cardiac disease states, extracardiac factors, and abnormal genetic control lead to the arrhythmia. We conclude with a discussion of the potential therapeutic implications that might arise from an improved mechanistic understanding.read more

TL;DR: Increased CaMKII-dependent phosphorylation of RyR2 leads to increased SR Ca2+ leak in human AF, causing elevated cytosolic Ca2- levels, thereby providing a potential arrhythmogenic substrate that could trigger or maintain AF.
