Cardiac memory was characterized by Rosenbaum et al. in 1982 as ST-T wave changes induced by ventricular pacing or arrhythmia that persist long after normal ventricular activation has resumed [1]. Rosenbaum's work enlarged upon the earlier studies of Chatterjee et al. [2]who reported persistent postpacing changes in T wave morphology. The key aspects of cardiac memory were that the magnitude and persistence of the postpacing T wave changes increased with the duration of abnormal ventricular activation (referred to as accumulation) (Fig. 1), and the subsequent normalization of the T wave occurred slowly, requiring hours to months, depending on the duration of the inciting stimuli.
