My episodes have increased to almost once a month which is very disappointing because they used to be almost a year apart. I go to emergency & get chemically converted. PIPs have not worked. Last year, an IV of metoprolol (beta blocker) got me back into normal sinus rhythm, but the last couple of times, the IV of metoprolol didn't work & I needed 2 doses of diltiazem (calcium channel blocker), given an hour apart, to convert me. These episodes were diagnosed as SVT.
Why would a beta blocker work one time and not the next time? Three years ago when I was first diagnosed, I went to emergency with squirrels playing in my chest. I was hospitalized & the intravenous calcium channel blocker doses did nothing, but a beta blocker converted me. Is there really no logic to this? Sometimes a drug will work, & other times another drug will work, and the same drug that worked before won't work, even though the diagnosis of SVT is the same? I have more questions but I'll save them. I get very weepy over this whole thing. Thank you!
