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

Left Ventricular Ejection Fraction (LVEF), Change From Baseline
From the iv loading dose during 30 min and the following maintenance iv dose during a maximum of 90 min. The infusion was stopped when all echocardiographic measurements had been carried out

To explore if AZD1305 compromises left ventricular performance in patients with left ventricular dysfunction.

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.

LAERP (Left Atrial Effective Refractory Period (ie, the Longest S1-S2 Interval That Fails to Result in Atrial Depolarisation))
Measurements were obtained twice, from the invasive electrophysiological measurements made before and 20 min (or more) after the start of administration of the investigational product

Absolute change, after - before infusion
