Exclusion Criteria

• •Prolonged QTcF \>450 ms or shortened QTcF \<340 ms or family history of long QT syndrome

• •* Intermittent second or third degree AV block (based on screening or pre-dose ECG)
• •* Incomplete, full or intermittent bundle branch block (QRS \<110 ms with normal QRS and T wave morphology is acceptable if there is no evidence of left ventricular hypertrophy)
• •* Abnormal T wave morphology, particularly in the protocol defined primary lead
• •* Dropped beats
• •History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD2115 and/or excipients
