چکیده

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Adaptive noise canceller (ANC) and independent component analysis (ICA) are powerful tools for separating signals from their mixtures. For better understanding of the mechanism and characteristics of AF, the artifacts were eliminated in the measured signals from atrial. We use ANC to subtract the influences of ventricle from the recorded signals, and manipulate the ICA technique to remove other artifacts so as to improve the signal-to-noise ratio of atrial signals. Keyword: Atiral fibrillation; Adaptive noise canceller; Independent component analysis

Protective effects of simvastatin on atrioventricular node during simulated experimental atrial fibrillation in vitro

Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...

Quantification of the transmural dynamics of atrial fibrillation by simultaneous endocardial and epicardial optical mapping in an acute sheep model.

BACKGROUND Therapy strategies for atrial fibrillation based on electric characterization are becoming viable personalized medicine approaches to treat a notoriously difficult disease. In light of these approaches that rely on high-density surface mapping, this study aims to evaluate the presence of 3-dimensional electric substrate variations within the transmural wall during acute episodes of a...
