Any suggestion that you have would be appreciated . Probably, your heart s conduction system has a number of potential problems, including the inappropriate sinus tachycardia and the PACs. A beta blocker, while it should decrease the PACs, could worsen the orthostasis. One suggestion, if you cannot live with the PACs, might be to treat you with beta blockers after implanting a permanent pacemaker. There are also other drugs for PACs, all with potentially bad side effects.
