结果正如最近的实验和理论研究 (8-11) 所确定的，心外膜电位反映了激活前沿与心肌纤维结构之间的相互作用。对于起搏或异位搏动，心外膜电位模式反映了兴奋传播的心肌纤维的方向（图 1）。利用这种关系，无创重建心外膜电位用于表征心肌壁深度的活动。
ResultsAs established in recent experimental and theoretical studies (8-11), epicardial potentials reflect the interaction between the activation front and the architecture of myocardial fibers. For paced or ectopic beats, the epicardial potential patterns mirror the direction of myocardial fibers through which excitation is spreading (Fig. 1). Taking advantage of this relationship, the noninvasively reconstructed epicardial potentials are used to characterize activity in the depth of the myocardial wall.
