To reduce current drain and thus optimize pulse generator longevity, 25 unipolar trailing tined leads with a 6 mm2 platinum electrode shaped as a dish were implanted in suitable patients and compared to a patient series in which 25 standard unipolar trailing tined leads with an 8 mm2 standard platinum electrode were implanted. Comparing the two patient groups there were no significant differences in age, sex, diagnosis or vein used. Comparing implant data: mean voltage threshold was 0.50 ± 0.13 V (standard deviation) for the group with the dish electrode and 0.60 + 0.14 V for the group with the standard electrode (p < 0.02). The mean current threshold was 0.64 ± 0.18 mA for the dish electrod..View full abstract
