Description:Augustus Desire Waller (1856-1922) "was the first to learn that the electric potential of the heart could be recorded from the surface of the intact body; in 1887 he obtained the first electrocardiogram or record of the potential variations from the human heart (Fig. 59). He also obtained electrocardiograms from excised hearts of laboratory animals in an attempt to learn the differences between tracings obtained with electrodes placed on the surface of the body and those obtained with electrodes placed directly upon the heart. - Waller made many observations on man as well as on animals. As a result of his studies, in 1887 he was able to predict, for the first time, the reversal of the electrocardiographic pattern in dextrocardia with situs inversus (Fig. 61). He was also one of the first to conceive of the single dipole to explain the heart's electric field. Although he did not use the term "dipole," it is obvious that he understood the meaning and, to some extent, the significance of the dipole concept. - Waller was not impressed with the diagnostic possibilities of the capillary electrometer. It was Willem Einthoven who saw differences between normal subjects and people with heart disease in the relatively crude records obtained with this instrument, and it was he who realized the need to record cardiac action potentials with greater accuracy. - Between 1893 and 1896, George J. Burch and Willem Einthoven advanced the mathematical theory of the electrocardiogram and devised methods of calibrating and correcting records obtained." George E.Burch & Nicholas P.
