This paper introduces some levels at which the computer has been incorporated in the
research into the basis of electrocardiography. The emphasis lies on the modeling
of the heart as an electrical current generator and of the properties of the body
as a volume conductor, both playing a major role in the shaping of the electrocardiographic
waveforms recorded at the body surface. It is claimed that the Forward-Problem of
electrocardiography is no longer a problem. Several source models of cardiac electrical
activity are considered, one of which can be directly interpreted in terms of the
underlying electrophysiology (the depolarization sequence of the ventricles). The
importance of using tailored rather than textbook geometry in inverse procedures is stressed.
