Now, 14 years and four editions later, these two men offer a sophisticated text of electrocardiography, using a deductive method. To provide a foundation for this approach, the first four chapters discuss the electrophysiological train of events in the normal heart. The generation, the spread of activation, and the regeneration of the vital cellular processes in the conduction system and the myocardium are considered in conjunction with the vectors of their electrical forces projected on the frontal and horizontal plane. In chapter 12 the relationship of these to three-dimension spatial cardiography is considered. The result has been a nice combination of the traditional pattern concept with vector interpretation to yield a better method of teaching, one calculated to
