The atria are anatomically complex three-dimensional (3-D) structures. Impulse propagation is dynamic and complex during both normal conduction and arrhythmia. Atria activation has traditionally been represented on two-dimensional surface maps, which

Abstract The site of earliest extracellular electrical activation in the sinoatrial node (SAN) is known to shift in response to autonomic stimuli, but the mechanisms underlying this phenomenon and the determinants of the location of dominant pacemake

Primary negativity does not predict dominant pacemaker location: implications for sinoatrial conduction

Autor: Richard B. Schuessler, John P. Boineau, Burt I. Bromberg, Dwight E. Hand

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 269:H877-H887

Activation sequence maps derived during normal sinus rhythm from extracellular potentials in the canine right atrium exhibit widely separated sites of origin. The objectives of this study were to characterize the distribution of pacemakers within the

Simultaneous epicardial and endocardial activation sequence mapping in the isolated canine right atrium

Autor: James L. Cox, Richard B. Schuessler, John P. Boineau, Masataka Mitsuno, Burt I. Bromberg, Dwight E. Hand, Tomohide Kawamoto

Publikováno v: Circulation. 88:250-263

BACKGROUND Since the atria are thin-walled structures, most studies that have examined the spread of activation in the atria have assumed that they behave electrophysiologically as a two-dimensional surface. It was the objective of this study to dete
