<prompt> Cardioselective beta blockers is contraindicated inCOPDII III degree heart blockAsthmaTachycardia  <response>: B II III degree heart block Except for those drugs specifically approved for use in heart failure, beta blockers are contraindicated in heart failure patients Side effects of beta-blockers are related to their cardiac mechanisms and include bradycardia, reduced exercise capacity, heart failure, hypotension, and atrioventicular AV nodal conduction block. Beta-blockers are therefore contraindicated in patients with sinus bradycardia and partial AV block. Non-selective beta-blockers are contraindicated in patients with asthma or chronic obstructive pulmonary disease which is not a contraindication for cardioselective beta blockers.
