The electrocardiogram (ECG) is a graphic representation of the depolarization of the heart. The physiology of depolarization of the heart is described in Chapter 5, and the particular pathways for conduction of the wave of depolarization are shown in Fig. 11-3. The ECG has undergone tremendous development and use since it was first applied to humans in 1887 by Augustus D. Waller.1 A brief history of the ECG is presented in Table 11-1.16
