A Portuguese study from 2018 on 30 patients with BrS and an ICD implanted found that 53.3% of the included patients had taken a nonrecommended drug, and that 6 out of 7 patients (85.7%) who had experienced appropriate ICD therapies had received a nonrecommended drug as opposed to 45.4% of patients without ICD therapies (difference borderline significant, P =0.062). 4 The authors found a mean time between therapies and unsafe drug use of 3.8±7.5 days.
