Intracardiac measurements of the evoked endocardial T‐wave were performed on 1,500 pacemaker patients. The sensed evoked T‐wave amplitude was found to be above 0.75 mV in 94.1 percent of all cases. No correlation was found between the amplitude of the spontaneous R‐wave and that of the evoked T‐wave. Some electrode characteristics proved to be more favorable than others for evoked endocardial wave sensing, i.e., a surface area of less than 12 mm 2 . porous surface structure (preferably carbon), and atraumatic fixation.
