心内电图对于诊断和治疗各种心律失常至关重要。为了获得有关底层组织结构改变的可靠信息，有必要正确解释这些电描记图。因此，必须理解其他参数如何影响信号。使用bidomain模型创建并模拟了逼真的3D几何形状。基于这些模拟，导管的方向，组织厚度和传导速度的心内电图的振幅的影响进行了评估。
Intracardiac electrograms are essential for the diagnosis and treatment of various cardiac arrhythmias. To gain reliable information about structural alterations of underlying tissue, it is necessary to interpret these electrograms correctly. Therefore it has to be understood how other parameters influence the signal. Realistic 3D geometries were created and simulated using the bidomain model. Based on these simulations, the influences of catheter orientation, tissue thickness and conduction velocity on the amplitudes of intracardiac electrograms were evaluated.
