Does not support dual-chamber ICDs to reduce inappropriate therapy in this cohort; leaves open need for randomized confirmation of device selection.
Does dual-chamber ICD implantation reduce inappropriate therapy compared to single-chamber ICDs in patients from the MADIT-CRT study?
Dual-chamber ICDs do not significantly reduce inappropriate therapy or increase complications compared to single-chamber ICDs in the MADIT-CRT population.
