Removing ventricular far-field signals in intracardiac electrograms during stable atrial tachycardia using the periodic component analysis.


BACKGROUND Intracardiac electrograms are an indispensable part during diagnosis of supraventricular arrhythmias, but atrial activity (AA) can be obscured by ventricular far-fields (VFF). Concepts based on statistical independence like principal component analysis (PCA) cannot be applied for VFF removal during atrial tachycardia with stable conduction… (More)
