• ii. Right or left axis deviation
• iii. Incomplete right bundle branch block
• iv. Isolated left anterior fascicular block (left anterior hemiblock) in younger athletic subjects
• QTcF interval >450 msec for males or >470 msec for females (the average value for the replicate ECG at screening and Check-In), or history of prolonged QT syndrome.
