Which of the following antiarrhythmics is a beta-adrenergic blocker?
Propranolol and Esmolol β-blockers (class II antiarrhythmics) also have antiarrhythmic actions. β-Blockers indirectly prevent calcium entry into myocardial cells; therefore β-blockers slow conduction velocity, slow automaticity, and prolong the refractory period.
Is diazepam a beta-blocker?

Are beta-blockers antiarrhythmics?
Class II antiarrhythmic medicines are beta-blockers, which work by blocking the impulses that may cause an irregular heart rhythm and by interfering with hormonal influences (such as adrenaline) on the heart’s cells. By doing this, they also reduce blood pressure and heart rate.
