Vectorcardiography plays a highly variable role in today's cardiology. Some cardiology centers attach a great deal of significance to it as an improved and more sophisticated mode of recording electrical potential of the heart than electrocardiography—perhaps the electrocardiography of the future. Some centers have abandoned its use altogether on the premise that it is primarily a research tool with little application for routine use. Many cardiology units take various intermediate positions between these extremes. It is perhaps justified to state that in very few institutions is vectorcardiography considered a sine qua non of cardiovascular diagnosis.
Winsor has undertaken writing a Primer on Vectorcardiography, commissioned by the International Committee on Standardization of Cardiovascular Methods, headed by some of the most distinguished names in world cardiology. By definition, a primer is an elementary text for beginners. Admittedly, the design of such a text is difficult for the reasons stated above. One might
