• •5. History of symptomatic cardiac arrhythmias or with clinically relevant bradycardia.
• •6. Any predisposing cardiac conditions for arrhythmia such as severe hypertension, left ventricular hypertrophy (including hypertrophic cardiomyopathy) or congestive cardiac failure accompanied by reduced left ventricle ejection fraction.
• •7. Electrolyte disturbances, particularly hypokalaemia, hypocalcaemia or hypomagnesaemia.
• •8. Any treatment which can induce a lengthening of QT interval, such as:
