Abstract
This paper presents a method for determining local 3-dimensional activation directions in human atria. We describe the measuring catheter used, the filtering of the raw signals, the detection of electrograms, and finally the calculation of the resultant vector which estimates local activation direction. This technique is then used to demonstrate that transient 'linking' of endocardial activation during atrial fibrillation exhibits sudden, not gradual, transitional behavior.
