本文介绍了容积导体不均匀性、模型误差和测量误差对反算心室除极等时线影响的实验研究。结果表明，在逆问题中，使用非均匀模型是必不可少的，确切的心脏几何形状（形状和方向）的知识是重要的，并且在正常ECG记录中遇到的信号误差（噪声）并不重要。发现所需的（测量）引线的数量为64的量级。
This paper describes experimental studies on the influence of inhomogeneities in the volume conductor, and model errors and measurement errors on the inversely calculated isochrones of ventricular depolarization. The results indicate that in the inverse problem the use of inhomogeneous models is essential, that knowledge of the exact heart geometry (shape and orientation) is important, and that signal error (noise) as encountered in normal ECG recordings is not critical. The number of (measurement) leads required is found to be on the order of 64.
