Fifty-eight patients fulfilled the inclusion criteria (mean age 47 +/- 11 years, 8 women). Thirty-six men (72%) but only two women (25%) had a spontaneous type-1 ECG at baseline (P = 0.02). Maximal ST elevation before or after drug challenge was 3.7 +/- 1.3 mm in men versus 2.4 +/- 0.7 mm in women (P = 0.007). The proportion of patients with a family history of SCD or an SCN5A mutation was not significantly different between both groups
