Last time I went to ER with this my BP mach and hospital finger pulse rate units could not read my fast afib. They found another pulse measure device they taped to my finger so they could see the afib and beats: constant 140-143bpm. They said anything over about 100 for long time should be trip to ER. Anyway, they tried 3 different chemicals in my IV over 1 hour, no change. Then they tried this last one, Cartia, and IMMEDIATELY it dropped to solid 80 - still Afibing around but at least it slowed. Took all of 1 second after they pushed it into IV. They sent me home with a prescription of it in pill form; next week my cardiologist when he did f-up visit said stop taking that stuff it is not needed. But I kept the bottle just in case... cartia xp cap 240/24hr. expensive @ $35 for 30.

What is a "RMSA?"
