Which beta-blocker is best for heart rate?
A cardioselective beta-blocker such as bisoprolol or metoprolol succinate will provide the maximum effect with the minimum amount of adverse effects. Beta-blockers that reduce resting heart rate less than others (due to ISA) tend not to be used for angina, e.g. celiprolol and pindolol.
