The results of stimulation threshold analysis carried out in 230 patients after the initial electrode implantation, and in 188 patients during pacemaker replacement, are presented. The electrodes investigated were the IE‐60K‐10 (279 cases), the IE‐60‐K (96 cases) and the ME‐50 (26 cases). The chronic stimulation threshold voltage for the electrode 7E‐60K‐1Q (electrode surface area: 10 mm 2 ) at a pulse width of 0.5 ms, after an electrode function time of 25 months, is 2.05 ± 0.18 V, representing 256% of the acute threshold, and is equally as high as the chronic figure for the JE‐60‐K electrode; 0.43 mA (291 %). On the basis of the computation of the stimulation threshold energy and the stimulation threshold charge, a reduction of pulse duration (a below 0.5 ms would not appear to make such energy‐saving sense.
