Abstract
Intraprocedural techniques for identifying a location of an origin of an idiopathic ventricular arrhythmia in a patient are presented. The techniques include acquiring an at least partial electroanatomical geometry; acquiring an electrocardiogram segment of the idiopathic ventricular arrhythmia; calculating at least one integral of the electrocardiogram segment; acquiring a plurality of pacing site sets of coordinates; acquiring a plurality of pacing electrocardiogram segments of the patient; calculating at least one pacing integral; relating each pacing site set of coordinates to at least one corresponding pacing integral, such that a plurality of coefficients are obtained; determining an estimated set of coordinates of the origin of the idiopathic ventricular arrhythmia based on at least one integral of the electrocardiogram segment and on the plurality of coefficients; projecting the estimated set of coordinates of the origin on to the at least partial electroanatomical geometry to obtain a map; and providing the map.
