There are 3 categories for electrocardiogram (ECG) findings: normal; abnormal, not clinically significant; and abnormal, clinically significant. Each of the findings was classified by the investigator according to whether it was normal. Abnormal ECGs were further classified according to whether they were felt to be clinically significant in the medical and scientific judgment of the investigator.

Maximum Plasma Concentration (Cmax) and Trough Plasma Concentration (Cmin) of S-carvedilol, R-carvedilol, and M4 Active Metabolite (SB-203231) at Week 8
Maximum Plasma Concentration (Cmax) and Trough Plasma Concentration (Cmin) of S-carvedilol, R-carvedilol, and M4 active Metabolite (SB-203231) were measured.

Number of Participants With the Indicated Change From Baseline New York Heart Association (NYHA) Functional Class at Week 8
The NYHA classification assesses the severity of symptoms of heart failure as judged by the investigator and is comprised of. 4 classes: I, no resulting limitations on physical activity (PA); II, slight limitations on PA; III, marked limitations on PA; IV, inability to carry out any PA without discomfort. The number of participants with any change from Baseline in the NYHA Functional Class at Week 8 was calculated. Improved=class at the visit is decreased compared to baseline class, Unchanged=class at the visit is stable, Worsened=class at the visit is increased compared to baseline class.
