Answer

Possible contraindications to beta-blocker administration include the following [6, 60] :

  • Heart rate slower than 60 bpm

  • Systolic blood pressure lower than 100 mm Hg

  • Asthma or chronic obstructive pulmonary disease (COPD) on beta2 -agonist inhaler

  • Active bronchospasm

  • Second- or third-degree atrioventricular block

  • Sick sinus syndrome

  • Decompensated cardiac failure

  • Pheochromocytoma (can be given in combination with an alpha blocker if the alpha blocker has been initiated beforehand)

  • Allergy to beta blockers

Beta blockers should be used with caution in patients with severe peripheral vascular disease and in patients taking calcium channel blockers.
