A member asked:

Was on metropolol -switched to coreg (carvedilol)-still having stuffed sinuses on coreg (carvedilol) also..why do beta blockers cause this..also what is sick sinus?

A doctor has provided 1 answer

Look for other cause: B-blockers have effect on bronchospasm but mostly not on allergy components. So look for other causes. Sick sinus syndrome (sss) is due to lack of signal from the sinus node to cause the heartbeats, therefore, other sources of signal take over which are usually slower than the rate which would have been from the sinus node.
