Course of Median DFT, Median Body Weight, and Median Body Length During Follow-Up
(A) During the first 36 months following implantation defibrillation threshold (DFT) increased by a median of 5 J and weight by a median of 6.5 kg. In contrast, median body length increased by 17 cm. (B) Course of median DFT displayed with box and whisker plots. The number of patients with serial DFT tests performed at each follow-up is displayed under the x-axis.
