New concepts, like good wine, mature slowly, and, ultimately, time tests their validity. The graphic representation of the cardiac vector is an obvious case in point. The limitations of scalar electrocardiography in showing the electrical activity of the heart led to the more precise but still imperfect techniques of vectorcardiography. This monograph presents a serious attempt to broaden further the fidelity of the spatial vector through the use of polar coordinates.
This is an impressive individual effort. For not only is the concept of latitudes and longitudes introduced as it relates to the cardiac vector and its application to clinical
