[A novel method for automated detection of activation time].
In the study of cardiac activity, manual determination of local activation times is a time-consuming process that precludes the application of cardiac activity during a clinical procedure or an electrophysiologic experiment. Based on former bipolar algorithm and unipolar algorithm, this paper presents a novel method. Using unipolar electrograms and bipolar electrograms simultaneously, this method determines the activation times with good accuracy.
