Do beta blockers weaken the heart?

Is diazepam stronger than propranolol?
Diazepam was more effective than placebo or propranolol. A reduction in the resting pulse rate by propranolol of more than 7.5 beats per minute resulted in a greater therapeutic response to this drug, alone and in combination. Lesser degrees of pathology responded better to treatment.

A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don't affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.
