Three-dimensional electrophysiological imaging of the intact canine left ventricle using a noncontact multielectrode cavitary probe: Study of sinus, paced, and spontaneous premature beats
Cardiac Pacing, Artificial
Ventricular Function, Left
Ventricular Premature Complexes
Noncontact mapping provides realistic, three-dimensional electrophysiological images of the endocardium, on a beat-by-beat basis, that localize the sites of origin of premature beats and reconstruct their activation sequences.
