摘要：

Electrical activity propagation along an electrode array within a cardiac chamber is reconstructed. Signals are sampled from the electrode array and the signals are plotted in multi-dimensional space with each axis corresponding to a channel in the electrode array. An excursion direction of global activation in the multi-dimensional space is estimated and a change in vectors of the sampled signals over time is determined. Signals with vectors that change over time in the excursion direction are suppressed.
