what is the difference between cardioselective and non-cardioselective beta blockers?
Non-cardioselective beta blockers, like propranolol or nadolol, helps minimize arrhythmias, blood pressure, heart rate, and the workload on the heart. ... Cardioselective beta blockers, like atenolol and esmolol, avoid the latter problem by targeting and affecting just the beta-1 (heart) receptors.
