Study Endpoints
Primary Endpoints
Dose-response Relationship for QTcF Interval of AZD1305
At any time post randomisation until end of Holter recording (18-24 hours post start of drug infusion).

QTcF-QT interval corrected for the RR interval (the time elapsing between two consecutive R waves in the electrocardiogram (ECG)) using the Fridericia formula.For each of 3 consecutive beats (5 consecutive beats if AF) a manual measurement, preferably in lead V2, of QTend intervals was done.The mean QT values of the 3 consecutive beats (5 consecutive beats if AF) were, together with RR intervals, date \& time of the ECG, entered into the eCase Report Form (eCRF).The selected beats had to be marked with calipers and noted together with measured values and calculations on the print-out and signed

Conversion of Atrial Fibrillation (AF) and Maintenance of Sinus Rhytm (SR)
Within 90 minutes from start of infusion

Conversion of AF to SR with maintenance of SR maintained for at least 1 minute

Maximum QTcF
During treatment days 2-10

Maximum of all QTcF values obtained for any given patient from randomisation until the intended end of the study drug period, day 10.

Pharmacokinetic variables
During all dosing visits
Secondary Endpoints
Wide QRS Tachycardias
From start of study drug infusion until discharge from hospital on study day 2.
Heart Rhythm. Number of Participants With Early Relapse Into AF.
Within 5 minutes following investigational product (IP) induced conversion, or direct current (DC) cardioversion, of AF to SR
Heart Rhythm. Number of Patients Remaining in SR up to 24 h Following Start of Study Drug Infusion
During 24 hours following start of study drug infusion
