• Clinical diagnosis of acute or chronic viral or bacterial infection with the exception of chronic recurrent herpes simplex infection
• ECG with clinically significant findings, including:
• Conduction disturbance (complete left or complete right bundle branch block or nonspecific intraventricular conduction disturbance with QRS ≥120 msec, PR interval ≥220 msec, any second- or third-degree atrioventricular block, or prolongation of the QT interval corrected according to Fridericia's correction [>450 msec male and >460 msec female])
