- •ii QTcF >470 ms, if QRS duration =120 ms
- •b If the subject is on citalopram, escitalopram, or venlafaxine (immediate or extended release)
- •i QTcF >425 ms, if QRS duration <120 ms
- •ii QTcF >450 ms, if QRS duration =120 ms
- •At Screening, if the set of triplicate ECGs has a prolonged QTcF due to an identifiable cause, and it is medically appropriate to address that cause, a repeat set of triplicate ECGs may be performed during Screening at the discretion of the Medical Monitor.
