Measure
Beta-blocker
In Group B, oral bisoprolol will be commenced at either 1.25mg, 2.5mg or 5mg according to the treatment schedule and uptitrated, as required, to 15mg daily. Recommended additional therapy in this arm includes diltiazem. Use of digoxin is explicitly discouraged but will not terminate participation in the study. If intolerance to bisoprolol occurs, investigators will be advised to try an alternate beta-blocker of their choosing (typically carvedilol, nebivolol, or metoprolol) at equivalent dosage. Bisoprolol: Drug intervention
Digoxin
In Group A, the maintenance dose of oral digoxin will be either 62.5mcg or 125mcg according to the pre-defined treatment schedule and uptitrated, as required, to 250mcg daily. A single loading dose of four tablets (250 or 500mcg according to target maintenance dose) will be prescribed in digoxin-naïve participants, where necessary. Recommended additional therapy in this arm includes the calcium-channel blocker diltiazem. Use of beta-blockers is explicitly discouraged but will not terminate participation in the study.

Recommended additional therapy in this arm includes diltiazem. Use of digoxin is explicitly discouraged but will not terminate participation in the study. If intolerance to bisoprolol occurs, investigators will be advised to try an alternate beta-blocker of their choosing (typically carvedilol, nebivolol, or metoprolol) at equivalent dosage. Bisoprolol: Drug intervention
Digoxin
n=81 Participants
In Group A, the maintenance dose of oral digoxin will be either 62.5mcg or 125mcg according to the pre-defined treatment schedule and uptitrated, as required, to 250mcg daily. A single loading dose of four tablets (250 or 500mcg according to target maintenance dose) will be prescribed in digoxin-naïve participants, where necessary. Recommended additional therapy in this arm includes the calcium-channel blocker diltiazem. Use of beta-blockers is explicitly discouraged but will not terminate participation in the study.
